Have two horns and know a 14 year old girl who is playing a bit and needs one. I have loaned them to her to try out. One is an L.A. Benge MLP and the other an AMC contempo. Are either of these horns suitable for her at all. Can she grow into them, etc. If so, what would be a fair price? The Benge is in reasonably good shape but with some bruises. The Contempo has lacquer deterioration but is basically straight and in good playable condition. Thanks for your expertise!
