Well, I'll go with the distinguishing tangent in regard to horns you tried, but didn't buy...
I was in USA Horn many years ago, gauging sales/trade interest in an SBA alto I had brought with me. I was there for a long day and tried nearly every horn I could. At the time, I was also playing a VII tenor and each and every Selmer off the wall, from the VI's to the III's, I preferred over the VII. But one horn in particular... a mustard yellow, ugly as all hell, brite-dipped five digit VI tenor missing a key guard... really wowed me. I was in the market for a VI at the time and offered two grand. I'd have gone up to $2,200, but they were stuck at $2,500, so I passed.
Often I think what might have been had I bit. Heck, I probably could have flipped it for double down the road. But not too long after that experience, I got to play some old Conn tenors and realized that Selmer was no longer for me. So I really can't regret not buying the horn, as I'm very happy with what I've got now.
