A dirt cheap clays gun? Nothing at all wrong with a Rem 1100 or something like a Winchester SX3 clays version. Last I looked, they were still pretty available in the secondary market. Must have an O/U? Find an old Citori field gun. Not too expensive and they run almost forever. Want a dedicated clays O/U that is not too pricey? Find a Ruger Red Label Sporting Clays in 12 or 20 with 30" barrels. I have one in 20 and I prefer it to my 687 (as a shooter, not as a looker).
