There are two tenors I'm looking at as backup for my 1967 Selmer Mark VI, as the Mark is becoming too valuable to drag out to bars for open mics and jams. One is a 1955 Conn 16m, the other is (I believe) a 1961 10m, both purported to be in nice shape, ready to play. The 10m is almost twice as much. I know the 16 m's have a good reputation, but I wonder if the 10m is more likely to hold it's value, and I wanted to solicit your opinions. Thanks, and looking forward to your replies.
