Well Cayugad has put up a good post as usual. In fact, he had talked me into getting a Genesis after reading his post on his. And for $135 + a $35 mail in rebate you can't go wrong.
If you want to go the traditional route I'd look into the Thompson Center Hawken. You may also want to check out the used racks for a T/C Hawken or Renegade. If you pick up a caplock one of the quickest ways I have found to determine if it was maintained properly is to check the area around the nipple and the bore. I've found that if the nipple area (the snail) is clean and free of pitting there is a good chance the bore is also in good condition. A CVA bore light is worth the price of <$10 for checking the bores of muzzies at the gun shop. Then check the lock to be sure it works properly.
Depending on you budget - the more you have the more choices you will have. But be forewarned - Once you start, you can't stop.
