The Beeman R7/ HW30 but its probably out of your price range. Second hand they do show up from time to time. The B12 is real nice and its price leaves lots of cash for ammo. One I would like to recomend but can't, cause I cannot get one to try, is the izzy 60 or 61. No ones got the darn things.
I am surprised that nobody has suggested the IZH60 or 61. Very low cocking effort, short and adjustable length of pull, and under $100. OK, it does not have blazing speed, just blazing accuracy.
Here's one that might work https://www.pyramydair.com/product/air-venturi-bronco-target-pro-air-rifle?m=2709
