I think even a plain-jane bottom-of-the-line gun that's in very high condition should be kept as is--as they used to say about land--they're not making any more. I'd say that about a Nitro Special or Win 24, not to mention an NID or a Field Grade Elsie. Anything else--it's a free country. Just do your homework and make sure that the "grade" is actually "up"!
