If memory serves me correctly I paid about $150 OTD for mine about 7 years ago.
Have no idea what one would be worth now. Haven't seen any in gunshops or at shows that I can recall.
Function has been 100% reliable. Not much on measuring group sizes, but I would say mine is capable of shooting around an inch or so at 50 yards.
I use it mostly as a "yard gun" for the occasional porcupine, skunk, coyote, etc that wanders too close to the house. Also take it out for a plinking session now and then - it's a really fun gun for that.
