The V-C is a very nice gun . . . and should be.  $18,000 for a boxlock.  The nonejector 12ga is pretty plain and likely overpriced at $900.  I saw a nicer "field grade" Sauer at Mark Beasland's just recently, and it's got that good Sauer name.  The last one, pushing $2,000, is bumping up against Birmingham 12ga BLE's.  And for better or worse, on the market, the Brit guns will usually win.
I think what those 3 show is that French guns are usually good, but it's harder to find real bargain-priced French guns.
