Once the supply dries up (who knows . . . 5, 10, 20 years) these guns will be well over $1K. Look at Mosin's, SKS's, Nagant Revolvers, CZ82...
Prices are all over the map right now, depending on the model. Anywhere from $275 for a cosmetically beat up police trade in 9mm to an easy 1 grand for a clean 10mm.
Check out Gunbroker. Look at 1076s, 1006, 5903s, 6906s, 4506, 908, 910 etc.
