I think the Scott Aspect looks pretty attractive with the Shimano hydraulic disc Brakes. REI sells it and I think they are having their summer sale coming up so that probably one that I would be looking at. In this price range I would just be looking at fit and feel. My guess is they are all 24 speed and although their wont be much difference I would prefer the option of 27 speeds and a cassette that has 34 teeth rather than 32 for some steep stuff. If you can afford a few dollars more I think 27 speeds and hydraulic brakes are nice. The Aspect meets one criteria.
