Depends what you want to spend. While the $400 Trek 4300 might do, you might really enjoy a $1000+ HT.

The mantra in the ski world is: Demo, demo, demo. This mantra is also true for the bike world.

Start with the big boys: Trek, Specialized, Giant, Kona. Then see what else is out there. Want something sweet, go for a steel HT. Salsa makes one. Google is your friend. For additional advice follow the link in my sig or try Mtbr.com forums.

Ride and then decided.
