Jefe - you may want to check out sportsdatallc.com. They're working on a simple self serve api for stats that would be very cheap (or even free) if you're not hitting it daily.

We're using them at StarStreet.com and have been really happy with them.

Let me know if you'd like an intro to them, we just split a booth with them at the sloan sports conference and their new stuff is really exciting.
