I like my Beeman P1. It's pricey, but it really is accurate. Maybe out of your price range from Pyramid, but occasionally a nice used one shows up at a gun show or online sale.
I have a nitro 22 cal break barrel rifle.
Under 200 bucks with scope.
Very accurate enough where I have eliminated ground hogs at 20 yards with correct shot placement.
I have the same rifle in 177 cal that seems a tad more accurate for target shooting but not for vermit control.
