My vote would be for the new Crosman 362 pump gun for around 100 bucks. It's based on the Crosman pistol pump gun design that's been around forever. It comes in .22 caliber and since it's a pump gun you have the advantage of varying the power level.
I didn't know they had brought those back. Crosman had stopped producing the multi pump 22 rifles for years. That would definitely be a good option. I may have to check one of those out myself.
You can still get the Benjamin pumper in 22, but the new style stock on it is terrible to trying to use open sights. I have an older one in 5mm, but the pellet selection for it is really limited.
The old Daisy 22s (basically an 880 in 22)were a pretty good rifle too, but again, discontinued for quite a few years now. It seems like everyone gave up on pumpers anything bigger than .177.
