Depends on what kind of clays game you want to play. Trap, skeet, shorting clays, five stand, etc. Different games require different guns. Purist in any of them will tell you to spend a butt load on an over/under. Lots of guys get by just fine with an auto loader. Pump gun is ok for trap, but most of the other games require doubles and a pump doesn't do so hot. Whatever you get make sure it has choke tubes so you can branch out into the various games. Skeet requires a pretty open choke, trap a tighter one. Sporting clays and five stand usually needs a couple different chokes.
