i played sax for 7 years through school, been 3 years or so now since i've picked mine up, it's certainly is fun to play though. Forget starting on tenor, the fingerings for all of the saxophones are exactly the same, a tenor will be more expensive, and alto is much easier to start on. The tenor and bari require more air to get sound, and IMO you'll want to get down the fingerings, vibrato and really just the feel for having it in your mouth before you move up to a tenor or bari. I did play tenor for several of those years, and do love the tenor, but still suggest starting on alto.
