Yes, Yamaha is BRILLIANT!
As mamianka said, if you can get a Yamaha, get it! They make great student horns as well as pro horns! I personally think that they make better saxes than clarinets.
If you want more options- look at Selmer, Buffet, Keilwerth, Yanagisawa and Conn. But you're good with Yamaha.
Have fun!
