Look at getting a best gun from a lower tier maker. The different tiers of makers and the prices they command have been discussed here in the past. For example-

Anyway, I always wanted one London gun, and 2 years ago I bought this 1907 HJ Hussey Imperial Ejector for under 6K. Its a definite lower tier make but a very fine gun nonetheless.
