Free Web Site Translators?

[grand]

Hey guys, im planing to expand my site to other languages. And i want to give our visitors a option to translate to their native language.
What is the best free translation program i can get? No software that i gotta install on my servers also.
Thanks

Most online translators are horrible and only give you the "gist" of what was said. My in-law sent me an email in Spanish which I ran thru altavista.com but it translated 'ano' as 'anal' instead of 'year'.

LOL. Imagine reading a letter from your in-law which has the word anal in it.
