I have a 22A. Bought it about a year or so ago. Got it and a leather range bag full of goodies, including a S & W knife, a can of pepper spray, and several other things, for $199. The value of the other stuff was in the $75 to $100 range so I figure I got the gun for $125. So far no problems with it. I put a BSA red dot sight on it. Just this Friday I took it (and several other guns) to the range. At 25 yards it is dead on "minute of squirrel." At 25 yards with it a squirrel is dead.
I also have a Ruger Mk II. I have had it for about 20 years. It has been super reliable even though I don't clean it nearly as often as I should. (I know, shame on me.) But it justs keeps on going bang every time I pull the trigger. It is pretty accurate too, but I just have the non adjustable open sights on it. By the way it cost me $6. I won it in a raffle.
My son had a Buckmark. After having to have it repaired twice, he traded it off. Basically it would become a single shot. After you fired it once, you would have to rack the slide (which would eject the unfired round) to make it fire again. Apparently when firing it, the striker would follow the slide down and would not stay cocked. When you operated it manually, it would stay cocked.
I guess the moral of the story is you can get a lemon in any brand. In fact, one day at the range I had a Beretta, a Browning, and a Ruger malfunction. The only one that wasn't the gun's fault was the Ruger. A cartridge case ruptured in my P89 and blew the extractor out of its slot. When I figured out how it was made, it was about a 5 second fix. Basically just push it back in.
