Anyone know how good (or bad) the Onkyo SR-608 receiver is? Or any of the other Onkyos? Reviews on it looked good and has a lot of pretty sweet features on it... 7.2 channels, 1080p upscaling, THx certified, 6 HDMI ports, and more. Just have started looking at whats out there and want to get some input. If not this brand... any other suggestions for the $250-$400 range?
