Note: for a crash-course in understanding the japanese-language as it relates to tfs, go here.
babelfish is one of the better free ones. I'd try this baby first. It gets pretty close, especially for that hard-to-translate japanese (I for one don't have that support for my current browser). I use this one most of the time.
Systran is almost as good as e-lingo used to be, and has become one of my new free favorites. Just make sure to pick the right order for the languages, or you might think it didn't translate for you :-) heheh. Limited in language choices, but aren't they all.
The ones below are useful, in a limited way (for me, anyways):
Web Dictionaries! Takes up the slack where other translators leave off. A huge selection of languages to choose from.
http://worldlingo.com/ Another machine translator, with paid serices for a human translator. Offers two versions of chinese on the free one :-)
http://www.yourdictionary.com/ Lets you look up individual words and meanings. Also has a thesaurus. Wee.
Pay to Talk to the Dutchbotters! Have a human being decode what Argus and Devvi are saying :-)
