Hey guys!
What do you think about Yamaha YAS 62 (professional) and YAS 275 (Student)? The last is cheaper,but what about sound quality in comparison with first?
Whats the best for me (i am beginner in sax playing) spend more money on YAS 62 model or YAS 275 more than enough? And which is easier to play?

I think as a beginner, you can`t go wrong with a classic such at the Yamaha YAS-23. It`s a classic, that model is pretty old and very good. The sound is excellent and it`s a fine marching instrument as long as u don`t need the use of the high F# key, which i doubt u`ll ever need in marching.
The YAS-62, i think that should wait a bit, it is more expensive. unless u know u`re serious enough to continue. Cuz eventually u`ll move away from the 62 to one of the higher custom yamahas or selmer super actions. but i still think, search around for a YAS-23, i`m not sure if u can find one new, but ebay, ur local classifieds. it`s a good horn, i promise.

Thanks, Jimmy.
Yamaha YAS-23 is good horn. But I`m from Russia and here is difficult to find that model. I heard many good replies about Yanagisava horns also(Yani 901 Alto for example). I like Jazz and my favourite alto player is Johnny Hodges. I need a horn for home use.
What models can you advise any more?
And which is better Yani or Yamaha (or differents aren`t large)?

Well i say look at your budget. Honestly, and in my biased opinion, a Yamaha will fair very well. It is without a doubt the best horn to use starting off.
I can understand dificulties of finding a horn, and even with ebay, some people might not ship to your place. I would just advise a Yamaha student, or an intermediate sax at the most. Let us know how the sax venture goes my friend.
