I just did that very thing. I got the 590LQ because I wanted the G. I was concerned because "you know what they say about Taiwanese horns"...... to be honest, I'm not sure about all of what they say, I'd just heard that "they" say "something" and it wasn't good. Apparently the 586 line and up is WAY better than the models of smaller numbers (from a few years back) as the manufacturer REALLY spent some time fixing the complaints about intonation and ergonomics (the 2 things I had heard that "they" say). The intonation is splendid. The tone is richer than the 1920-ish one piece straight Conn that I've played on for 10 years. While I've never played a Yani that this is the copy of, I understand that its an excellent copy visually and tonally. The ergonomics are very good (not quite splendid...read on). The high d palm key sticks out far enough that my fairly large hands can reach it with ease. I'm not thrilled about the travel distance of the octave key; it seems a bit long, but I think I could have that adjusted or put a half-moon of cork on the octave key. Anyway, coming from that old Conn I'm in heaven. I highly recommend it, and I'd suggest you chat with Dave K or his Dad about it (i know, i know, like chatting with the foxes about how to best pen up the chickens) as they're happy to "sell you" on 'em & answer oodles of questions. Its fabulous. I have no regrets.
