I have books going through for a few languages.
Pro:
It's money that I would not have gotten otherwise.
Con:
Not all translators are created equal.
Aside from the fact that the actual translation part is very difficult, you also want to find a translator who is willing to help you promote afterwords. Since I don't speak any of the translated languages, it is tough for me to post to facebook groups, or do any sort of promotion.
One of my translators actually started a mailing list for the translated books, and had all of my english promo materials translated so she could use them to pimp the books, which is fantastic.
You may want to talk about stuff like that up front. Or at least mention it in your author bio.
