You could try Google's translator (Select the "language tools" link on Google's main page)
or click here

One of the best (IMHO) is Intertran from
http://www.tranexp.com/
However it is now a paid for product only, the website nolonger offers the free option of typing in what you want translated, click here and hey presto.
