I have a new system with a 522 and it sucks, nothing good to say about it. I am considering swapping it out for a 510. What do you all have to say about the 510? Is it a reliable machine, without all the sound dropouts, audio popping when changing channels, and frequent picture distortion that I have every 5 minutes on my 522??? How would you rank the 510 on a scale of 1-10, with 10 being perfect? All input appreciated!
