Would agree with the Beeman R9 also, but if money is an issue, the HW95 is the same gun (slight cosmetic differences) but $150 less. Can't go wrong with either one IMO.
I'll have to go along with the rest on this recommendation as well. 177 vs 22 would depend upon the game I was going after. I've use an R9 and an old FWB 124 in 177 to kill quite a few squirrels over the years. I'd avoid the cheap Spanish and Chinese made guns unless that's all your budget would allow.
