WTB: XC Bike

Edit: Have lots of parts I can work out a trade with, or will pay cash.

I am looking for a good deal on an XC bike. My little brother would like to get into XC, and his current bike is a little to heavy with too much suspension. Would prefer full suspension, but would entertain a hardtail as well. Looking for a size medium frame. 3-4" of travel.
