Re: Suggestions for a good Tenor, reasonably priced....
YTS's have a good reputation for intonation, but the mouthpiece can certainly make a difference here. Otherwise, yes, renting is a poor option for long-term ownership. here's some models to look for:
Buescher 400 (Late model with floral engraving, the TH&C version may be better, but costs 3 or 4 X as much) I got mine from a local retailer for $600.
Yanagisawa 800 or 880 Model. Yani's pro model during the 1980s. Not too many people have complaints about Yanagisawa in general
Yamaha 61 or 62. Probably a bit more $$ than the other ones, and not to my taste, but good reputation.
