possibly try a guitar center. There's probably 80 of those around SF
To be honest though, I've never seen those in stock anywhere (granted, I don't frequent stores that sell wind instruments, so it might be different there). But if he's going to be there for a bit, you could probably even have them order it (if they don't have it in stock). Places like GC can get stuff in a week or two, even less if another store in the area has it.
