I've had 3 Pioneer decks, currently the DEH-P7000. Te only reason is I worked at Best Buy and got fat discounts on them, and Pioneer was the best they had.

The biggest downfall of Pioneer, IMO, is the FM reception, it has always sucked on all the decks I've owned.

Someone posted about SN ratio. This is where you do you shopping for quality. You should get all the measurements that matter to you, like FM sensitivity or stereo separation or RCA output voltage and pick 3 decks. Then go play with the decks and see which one you like the best.
