Thanks.
I've decided to go new. Looking at the Trek Marlin, Trek Wahoo, Felt Nine 80, Giant Talon 27.5 5, GT Karakoram 4.0 MECH, or the Specialized Hardrock 29 Disc.
Still doing my research. I've rode the Marlin and the Nine 80. I think I liked the Nine 80 better, but it was a frame size one bigger then I would typically ride (I find that I am in between frame sizes).
I'll be spending more time researching and test riding when I get a chance. I'm looking at making a purchase in the next month.
