SYSTRANET
Though Yahoo! Babel Fish and SYSTRANET are both powered by SYSTRAN, SYSTRANET provides more languages and may be the better choice between the two options. Once you register for free online, you get access to additional features such as RSS translation, file translation (doc, docx, rtf, htm, html et txt) and creating a personal dictionary. These extra features are absent from most machine translation tools, so it may be worth taking the time to register an account with SYSTRANET.
