Giant Reign? I think. I got a Trance, the 5 inch travel version. If you can get that for 350 and its in good working order then that sounds like a bargain. In addition to the normal things, lift the bike up from the seat and you will feel if there is any play in the suspension bushings, like a little knock. It is all replaceable, but something to factor in if there is any significant play. I think the fox shocks and forks are pretty reliable but do some research on those specific models and remember its usually not as bad as the Internet makes it out to be!
As far as riding them, they are amazing bikes. The a reign is a bit more downhill/free ride orientated but they pedal just fine up hills and to your local cafe
