I have an old Beeman R9 .20 caliber that I shoot the pee out of. Have worn out/replaced the spring a couple times, but that is cheap and easy and you really have to shoot it a lot over a long period to wear one out.
In it's current state of tune, it runs the JSB Exacts at 700 fps and the HN FTT (which it is more accurate with) at 770 fps. Those aren't big velocity numbers. But, those are much heavier pellets than the .17's you are using now. Go right through a gophers head at 40 yards. And more to the point, it is accurate enough to hit a gophers head at 40 yards.
Excellent trigger, known for really good accuracy, I think you would not go wrong with a Beeman R9 or for more power, an R1.
There are a lot of good options in the same general price range. RWS is one. There are others. I really like the Beeman trigger though.
