Looking at Raspberry Pi, but don't really know anything about XBMC except it runs great on Apple TV 1 which are about $125 used.

I want to get something well under $100 that has BT kb/mouse support & wifi capable.

I would like an answer to this question as well!

You answered your own question. A Raspberry PI would do the job. You will also need a memory card and power supply.
