Dual suspension any wheel size is pretty expensive if you want a decent one. You can drop down to around $2k and still get a pretty good one.

Well I see my link didn't work but anyway Diamondback has some decent full suspension bikes in the $2k range at online stores. Won't impress your buddies but they ride well, biased since I own a sortie 29er
