the diasy 22 is a very good gun, i have seen them new for that price. I have a 2200mag crosman and i like the 22 pumpers, also the 22sg is going like 550fps, cropsman 2200 is 600fps, the Benji 392 is 670fps all with cropsman pointed. the 22SG is a very good 30 yards or less hunting gun for rabbist,coons, and there like. Co2 have the problem of that they don't hold air well, and you have to buy more co2 later. If i were you i would get a pumper and be happy with it. also 10 pumps for most pumper but the crosman 2200 &2100,Sheridans only 8 pumps for full power, more then 8 for those gun can mess them up and they lose power past 8 pumps.
