What online language translator do you use?

I frequently need to translate chunks of text from other languages, mostly German, to English.

Google translation is ok if one has enough context. But results are often hilarious. For example, the following text:

"Bitte überschreiten Sie die Upload-Limite von 1 MB pro Dokument nicht! Es können sonst Upload-Probleme auftreten."

... was translated to:

"Please exceed your upload limit of 1 MB per document, it can otherwise upload problems."

Are there any online translators out there better than Google's?
