i do not live in houston but i have 5 yas-23's to chose from at different prices. they start at $325 and go up to $ 800. the $ 800 is like new with about 5 hours of play. i have one for $ 600 with about 1 year of play. one for $ 385 with new case. cheaper horns have some wear in the lacquer but keys, rods, etc are tight. i have one for $ 350 and one for $ 325. all are ready to go. fully adjusted and oiled. no leaks.plays perfectly. one of the horns needs a new E flat pad because it is stiff, but does not affect play at all. I have a couple of references here from folks who have bought 23's from me . all prices do not include shipping and insurance.
