It's not the best by any means, but the only guns I evr had under $100 were Jennings .22s at $60 brand new. They had almost no rifling but were great fun little plinkers. I had one that had a bulged barrel because of an ammo problem, and Federal bought me a new gun. I shot that one until it was worn out. You could buy enought Jennings .22s for the whole family cheaper than you could buy one Walther TPH which is what I really wanted. I have a Yugo budget and Cadillac taste.
I had one of those, Guy sold it to me for $20 because it would not chamber a round. I used a round file to remove the burr his dry firing had pushed into the chamber and sold it for $60
Another $20 deal was a guy at work had a "380" that didn't work, He said "it's such a peice of crap I'm going to throw it away" I offered him $20 and wound up with a like new Accu Tek that worked perfectly after I turned the saftey the right way, sold that for $90
