Since you are playing an 80 year old Buescher and enjoying it, I'd say you might look into adding "old horns" to your search. Just find a good, reputable tech. Tech's can do great things with a decent vintage specimen for not a lot of money. Considering what they can do, having access to a good tech is a relative bargain. The lure of older vintage horns, is discovering the many underrated horns out there, rescuing a nice find, and enjoying something from the hey dey. It also can be a cheaper way to own a superior horn. But, its not for everyone.
