I didn't hear you say you might only get $130 for another air gun!
Consider the RWS 48, in 22 caliber. It is heavy, but it drives tacks and hits about twice as hard, with one stroke of the side lever, as a sheriden 20 cal pumped 15 times, which is max vel. Sound is a bit less with the side lever I believe, and no starling gets away out to at least 50 yards. Best pellets I've tried are the RWS pointed field pellets, which are light weight, move fast, penetrate deep and wound large enough to kill quite clean, by airgun standards. I would prefer wadcutters for ranges to 40 yards on most pests to 2 pounds weight, as the flat nose will out kill any other form, if it is sent out with enough power to penetrate through the vitals, whcih it will be in this rifle. The 20 and 177 calibers in the same gun are excellent also, for lighter critters with each step smaller in caliber, but I chose the 22 so I could use it effectively on feral cats and skunks. It definately is effective on these out to 50 yards. Hitting is easy out ot 100 yards on pests down to our Idaho gophers or ground squirrels, which weigh I guess about a pound, but most will provide their own funeral, by running down their hole before expiring.
I bought what I believed was a high quality barrel cocker, twice, and those will be my last. If the barrel moves at all it won't be accurate, and the barrel WILL wobble after some use.
As for any pump up. They are all made for kids, and their saftey so far as excess pressure is the most indiscribably inefficient pumping system possible. So you pump for ever to get decent power, and that barely decent. Accuracy with the fixed barrels has been excellent with the three I've owned, but the report on firing is louder than spring guns.
