I too have been looking for a 29 in the $600 price range. Depending on where you live (someone found a 2011 Trek/Fisher Mamba for $679 in Delaware. Of course Im on the other side of the country.) My LBS has a Diamondback Overdrive for $650 or a '09 Fuji Tahoe Comp for $699. I cant say about anything with FS. Im too heavy for anything like that. Good luck.
