I am not aware of a “STARS 2” and you may be thinking of the APCO Project 25 Phase 2 digital trunked radio system however at this time STARS is Phase 1 so any digital scanner should work. That said there are so many Phase 2 systems coming on line that you may consider purchasing a Phase 2 capable scanner if you can afford one. Just a thought. Anyhow the Uniden 396XT is a good Phase 1 scanner. Check ebay. Then there is the new Uniden 436HP which is a Phase 2. Whistler is supposed to pick up the GRE line but we are all waiting for that to happen. Maybe in June? You probably should visit the scanner page for more information. Good luck.
