I would say really look at the HT. As mentioned before, in that area that is plenty to work with. A 29er would help absorb a lot of the little bumps that you will see. In the end find the best bike that feels comfortable for you with the best component setup in your price range. Don't be afraid to try and work a deal with the LBSs espcially on older frames ('08s, '07s, etc). They are a lot more willing to deal on older frames that they need to move.
