If your question was what type of saxophone to buy, I would recommend you to buy an alto in the key of e-flat. They are the most common and cheapest and the easiest to get started on. As for saxes, depending on your price range, the Yamaha YAS23 and the Selmer Bundy II are wonderful starting saxes, especially if you can find one used. Stay away from those colorful ebay saxes that are $100 or $199 or something like that, they are made in china crap that will only make beginning saxophone arduous and could even turn you off saxophone. As a long time sax player myself, I can tell you that you about to enter an amazing and enlightening world. For all the information you could ever use, go to
