Oh please, if one has $500 to spend I would look for older extractor guns from: Beretta, Sakaba or B.C. Miroku. Ejector gun or 20ga will bring few hundred more. The Sakaba 'Royal' is poor mans copy of W&S 700. English Webley 700 is better than inexpnisve Spanish double just like French Brie is better than one from great state of Wisconsin. smirk
For <$500 something ugly, basic but long-lasting from GDR, USSR, Czechoslovakia, Yugoslavia or Hungary can be found.
