Steve,
$10k for something special? Perhaps a once in a lifetime purchase?
How about something made for you such as Rich, aka C.O.B. had made for him or rather for his dog Gunner:
The total cost of Gunner's Gun was over $10k but not that much more...
Another affordable custom belongs to PGCA member Greg, aka Wild Skies. It is a wonderful AH Fox 20 gauge which was custom made for Greg for under $15k:
PS: Both guns shown were engraved by Robert Strosin of RES Engraving.
