You can get a new Searcy PH in 470 NItro for about $10K. You can get a new Krieghoff for about a thousand less and a new Blaser for just a little less than the Krieghoff.

One thing to consider is there is a differencem in price in almost all doubles, when you go from a medium bore (9.3x74R and down) to a big bore. Take a look at www.gunsamerica.com in the their "double rifles" section for some prices for new and used double rifles. There is also a section on "krieghoff rifles" and "sig rifles" where Blasers are listed.

It's a little far from Pennsylvania but their is new store here in Southern California called "Ivory Beads" that is exclusively high-grade guns....mostly side-by-sides in shotguns and rifles. They are dealers for Searcy and are very in-tune with the market on quality guns and they are a pair of really nice guys who realize you don't need to retire on the proceeds of each sale. Take a look at their website www.ivorybeads.com The A.W. Wolf 9.3x74R they have is a piece of art...photo doesn't do the engraving justice.
