Where is an accurate online translation guide?

Any one know of a site other than babelfish that will accurately translate one language to another? I am going with some friends next weekend to get another tat, and I am not fluent in Swedish, though the phrase that I want to put on my body, I want to put in Swedish, not English.
Update: The phrase, Ronnie, is : To Love is to Burn, is to be on Fire.
