Ken,
Dig (alias Smallbore) is not blowing his own trumpet enough! If you want a good one at the right price I believe Dig wiould be able to source one for you direct from a London Auction - he will have the choice of many many examples in your price bracket, (something which would not normally be possible as many US dealers will not have in stock the shear number or choice of London guns that are available at these sales.
I wouldn't hesitate to go this route myself If I was resident in the states. Failing that hop on a plane and spend a little time in London whilst you visit the auction houses !
