You should be able to find a nice Beretta SO3 EELL or a mid-80s SO6 in the 10-15K price range. The mid-70s SO guns will be in the 7-8lb range. 28" barrels are easy to find; the 30" will be a little more difficult. The SO2, SO3, and SO3ELs will be less expensive. The SOs are hand engraved with a lot of hand fitting.

The CSMC A10 is a Galazan clone to the Beretta SO series.
