If you are looking into gaming the 1200 is best. Petro Tyschtschenko sold a few NOS 1200s. I got one and it runs great. I also had 4000D s but beware of cap leaks battery leaks and distorted sound. If you get a 1200 make sure you recap it, same goes for a 4000. 500 and 2000s dont need recapping mostly. I have a spare A2000 if you are interested. Send me a PM.
