Fact is that there aren't many stores that carry more than one new tuba at a time, fewer by far that will have any real selection of pro-level instruments. Euphoniums are essentially the same story.
Is there another west coast dealer besides Steve Ferguson that has a "real" stock?
Just off the top of my gray but still hairy head, there are only a few in the US that I can think of. Any that I don't mention specifically, please don't take offense but add onto the list, please!~!!!!

ok....have at it, everyone. Add your favorite dealer with lots of stock to choose from.
There are MANY who are authorized resellers of instruments, but don't really keep things in stock. I apologize for not listing all of them, but that's a tough list to conjure.
