Generally speaking, if you have plans of getting into paper punching, I'd suggest one of todays semi auto of decent quality. Picking which one is much like deciding what PU truck to buy, Dodge, Ford or GM. If you have the opportunity available, get in with guys at a local club and try a few out before you decide. Also, this isn't to say a decent semi auto can't be used for plinking but for my money, if plinking was going to be my game, I'd likely go for a good revlover.
I still have trouble deciding,

hence the present vatiety
