Quote: "or for guitarists a Squier instead of a real Fender."
Never never never never. The sound of a guitar or any instrument depends on these three things: the shape of the material, the quality of the material, and the type of material. Squiers are factory produced cheap things, Fenders are factory produced with decent material, and Custom Shop fenders are hand made out of the best materials. It's pretty easy to say which sounds and plays better, and I'm sure the same goes for saxophones. If a Trevor James tenor is handmade by a professional quality tech, you can be sure it will sound good.
However, I do ask that you actually try one first (though it may be late now), because good as it may be, it may not have the tone you want. My friend is a drummer, and he always buys sabian or paragorn cymbals. Zildjians are good, built the same way as Sabians, but they're far too flimsy and weak sounding for him (I hate the way they sound), so he buys Sabian. Certian flavors for certain people, and if you know you'll like it (or you can return it), then get it. Otherwise you'll have a chunk of brass you won't like.
