To me the big decision is whether or not you want 29" tires. If it makes no difference, and if that Specialized is truly a Stumpjumper, not an XC, then I have to point out that the bike WAY underpriced. Dual sis Stumpys regularly sell for over 1K and in the only ridden twice condition stated, if true, it's worth around twice what it's listed for. If it's just the FSR XC model, the $600 price tag is still a good price, but not a great price.
Actually, if it's not a Stumpjumper, I'd pass and opt for the Giant Talon 29er. You can check out the Scott, but my experiences with pawn shops is that they are not clued in depreciation and usually want more than the bike is worth, but you're in a different location and that may not be true where you are.
