I'm completely new to recievers. I've run my 720P DLP, surround sound, and dvd players straight to there intended locations for several years without ever using a reciever. I am also thinking of getting a projector as well. What's a good reveiver for a low-to-medium budget? This Sony - STR-DG1000 ($540) looks pretty sweet I think. Is this one da bomb? Opinions would be much appreciated.
