I'm really happy with my C'dale Gemini. Solid bike.
If you can get a hold of anything FSR (specialized rear suspension) go for it. Single pivots are fine until you become a better rider, then they become a pain in the ass if you're riding hard (brake jack). If you can find a Big Hit, go for it. The Norco Shore series is kick-ass too, but I'm not sure what they go for. FYI Norco also uses FSR, it's basically a more budget way to get that suspension than Specialized.
The Ironhorse 7point series look awesome, but I don't know much about them, except that they use DW-Link (used on Team Sunday, and the technology similar to Maestro) which is supposed to be AWESOME in terms of pedal feedback and brake jack.
I'm hoping on scoring a Demo 8 in the near future. The 2007 ones look sick.
