One note though... since you are six foot you're not going to need a 22" frame! You'll be looking at something a bit smaller. Especially if you are going to be getting into any rough trail riding(anything will ruts, logs...and some things you'd find on...say a hiking trail) I'm 6' and ride a 19inch HT.... I also ride an 18inch for the more urban/tech stuff.
Oh if you're lookin for a good bike cheap I have two of this bike at my shop(2002 Specialized Rockhopper)... Private Message me if you're interested! Look for the PM at the bottome of my post that's how you'd PM me. I'll sell it extrememly cheap! ANd it's never been riden.
