Any tips for a decent quality saxophone?

I have been playing a tenor sax for 3 years, and I'm really enjoying it. I was thinking about getting my own, but I am looking for one that is under 1000$. I just want to own one, and I need some tips of where I can find one that will play a nice tone, and not too expensive. Also, and tips for where I can get any accessories such as mouthpieces, reeds, etc. thanks for your guys support, and any ideas you guys have.
