I just last recently picked up a used 625 Mountain Gun (4" tapered barrel) in 45 Colt for $500. It has some holster wear but otherwise is in very good condition. The new stainless Mountain Guns are running around $850 to $900 and are hard to find at that price (same price for 44m and 44 colt, it seems, though the 44acp JMs are more expensive). Just as a price point reference. Two weeks ago I picked up a 610 4" used in excellent shape for $600 (private party, no sales tax). Same frame and these should sell for the same price (short term fickle demand not withstanding).
