Hi Sara,
Here is another alternative that has gotten good reviews. It is a German music store brand but they ship to the States and have good customer service reviews. The silver plated model is not much more than 1K and they have a "scratched lacquered" model that is a little cheaper. I like the looks of it better than the silver plate! I believe there is a link to a video review of this horn somewhere on this forum.
Best of luck in your search!
