... or, for that matter: "Your horn's broke? No biggie. Here's another."
I do think that this boils down to one question: "Would you recommend this horn to a beginner?" (Even assuming that all the tweaks we've and SOTW has mentioned have been applied.)
For me, I just really can't see doing it. Even if this horn is as good as, say, a Yamaha 23, it's never going to be as sturdy. I could see me saying something like, "If you ("your kid," whatever) isn't going to take care of the horn, the Vibratosax is worth it. If you aren't, then you should go for a used Yamaha 23."
I could also see a place that rents out student horns wanting to switch to Vibratosax because the horns are cheaper, but I've seen rental horns and I know that they can get pretty beat -- or can be really old (hey, Kessler leases Bundy IIs. They haven't been made in what, 30 years?).
I'd like to know the terms of that Vibratosax warranty. If it's a full replace of the horn if there's any damage, I can start seeing the above scenarios happening.
