If they don't have a 9.3 Lux in stock in the US, I guess I'll go back to looking the Gun List for used ones, as well as Whitworths.

These guys have an unfired 550 Mag in .375 H&H for $625, but after I paid shipping and FFL, I can get a brand new one from my dealer for less.

This gun store also has a used .458 with muzzle break on the rack but its stainless and synthetic (blah). Little too much gun for me I think.
