Don't forget about the hand made Guardalas. I've seen some of them go for almost 2 grand.
Totally forgot about them. They are probably the most expensive tenor pieces.
I can't think of anything too obnoxious on baritone other than the Gale pieces. Vintage Berg's seem to be going for a lot of money these days. I don't really see the point but then again I generally don't see the point of paying that much for a mouthpiece.
