I'd love to get a great deal on a used bike, but I really have no idea in what i'm looking for in the bike to know if it were a great deal or not. If anyone knows of any good deals, send the link on by assuming you don't keep it for yourself!!!

So far today, I've looked at and rode 5 bikes:

1. Raleigh mojave 8.0
2. Specialized Rockhopper
3. Specialized Hardrock
4. Haro Escape Sport (had a Escape about 4 years back that kicked ass, I love these bikes)
5. Gary Fisher Pirahnna

Out of all of these bikes, 4 were in my price range now. the rockhopper, hardrock, '06 mojave 8.0 for $549, and the gary fisher.

I rode them all and honestly liked each one. They all felt different, but nothing I didnt like. Which out of these is the better choice?
