HOW TO BUY A USED COMPUTER

(First Published in the March 2003 Issue of  The Miser's Gazette)

Reusing some of the ideas from one of my first Miser's Gazette article, this month, I will provide a brief overview of things to consider when purchasing a used personal computer (PC).  Since there's some terminology common to new and used computers, those of you considering a new computer may also enjoy this article.

If all you plan on using your computer for is word processing, an occasional spreadsheet, and regular Internet surfing, there is no need to waste your money on the latest computer technology.  By buying a used/refurbished computer, you are not only saving money but you're also doing your part for the environment by delaying the dumping of lead, mercury, and other toxins, commonly found in computer equipment, into the landfill.

In the last year or two, many computer stores have recognized the demand for used and refurbished computers so finding a reliable used computer should not be as difficult as it once was.  A typical used PC may contain a Pentium 166MHz, 32 MB RAM, 1 GB Hard Drive, CD-ROM, 1.44MB Floppy Drive, and 56K Modem.

Now what does all this mean?

Processor: Consider this the "brain" of the computer.  It is also known as the CPU.  There are several types of processors available (primarily from AMD and Intel).  The computing 'power' is most easily measured by the speed (MHz/GHz) of the chip and is dependent on the applications used.  Note that 1GHz is equal to 1000MHz.  The 'larger' the number, the 'faster' the processor.  Just to let you know, we have now surpassed the 3GHz mark for CPUs!!!  For typical home use, such processors are simply overkill.  For those who plan on using their computer for the Internet, word processing, and the household budget, a 166MHz is a comfortable minimum.

Memory (RAM): Random Access Memory is the 'thinking space' that the 'brain' uses to perform its tasks.  Once again, the larger the number of megabytes (MB), the better.  (16MB is okay but ideally, you should look for at least 32MB in your used computer purchase).

Hard Drive: This is where all of your computer files and programs are stored. 1GB minimum (the more, the merrier).

CD-ROM: Allows you to store and use programs on a compact disc (4X speed minimum).

Floppy Drive: Although it's becoming obsolete, your used PC should not be without a floppy drive.

Monitor: Don't be cheap when it comes to your monitor purchase because this is the piece of equipment you'll be staring at.  Many stores offer good quality refurbished monitors for less than $100Cdn.  Pick one that feels comfortable (minimum 15-inch colour).

Modem: To connect to the Internet, you'll need a modem.  Though you may able to establish a high-speed connection to the Internet with your used computer, it might not be worth the money as you probably won't get the most out of it.  Though not as blazing fast as a cable or DSL connection, a 56K connection is still more than sufficient for checking your favourite web sites and email.  Make sure you have a 28.8K (preferably 56K) modem installed.

Printer: If you would like to print out material, you'll obviously need a printer.  With brand new ink jet printers at extremely low prices, there's really no good reason not to get one.  In fact, they're so cheap that some people buy a new printer each time their ink cartridge runs out as buying a new cartridge is sometimes more expensive than buying a new printer (that includes a cartridge).  Others avoid the high cost of cartridges by using ink refill kits.  Special Note: Most new printers use USB technology.  If you plan on buying a new printer, ensure your used computer has at least one USB port to avoid the hassles of additional upgrades or adapters that may cost as much or more than your used PC purchase.

Warranty: Reputable computer stores usually provide some sort of warranty on their used/refurbished computer equipment.  Since you're dealing with used equipment, you should make sure your purchase is under warranty (21 days minimum).

Operating System: Here's where things might get a little pricey!  Depending on the store, your used computer may or may not include an operating system; without one, good luck using your computer! The operating system tells the computer what to do and simply makes your computer experience a lot easier.  If the computer comes with either Microsoft Windows or Linux, then you have nothing to worry about.  Otherwise, it depends on how much are you willing to spend as purchasing a Windows license can cost you as much (or even more) than your used computer while Linux is either free or available at a relatively low price.  If you don't plan on using specialized software, and simply want to surf the Web, type a letter or spreadsheet there is no reason why you should waste your money on Windows.  There are many misconceptions of Linux and the lack of software is one of them.  Whatever your choice, make sure the original CDs are included. 

For those of you who would like to utilize your PC for more intensive computing activities such as gaming and multimedia (ie. digital photography), you'll have to consider a higher-end refurbished machine with a faster processor and CD-ROM, a dedicated graphics card and sound card, USB ports, and more RAM and hard drive space than the above recommendations as they are not be suitable for your needs.

The performance improvements on the hardware side of computers have outpaced the demands of software applications.  As a result, you can waste your money on the latest piece of equipment and not see much improvement in your computing experience.  So before you head out to the store to buy a computer, figure out what you'll be using your computer for.  If it will be simply for basic computer applications such as word processing and the Internet, your pocketbook will be better off with the purchase of a used or refurbished computer.
