I can only comment on firearms I've owned.
1. Stoeger Condor II, I had one about ten years ago, every time I pulled the trigger it would double. I sent it back to the factory for repair, it worked fine for about 2 boxes, then it started doubling again. Last year I purchased a Browning 525, my buddy told me I was stupid for spending $2500+ on a gun. He went ahead and proved me wrong by buying a Stoger Condor II, guess what, same problem.
2. Savage ( rifle ), I've never owned one but have fired one. They seem accurate enough, but when you shake them it sounds like there are BB's in the action.
3. H&R heavy barrelled 17 HMR, 3" groups @50 yds. I thought what a P.O.S. round, until I bought a Ruger, .88" @ 100 yds.
So if you like cheap guns, more power to you, I just haven't had any luck with them.
