I also have a DAS 6, bought a few years ago, am an amateur user but found it easy and excellent. Not the only "amateur" DA polisher on the market, but I'm quite happy with mine! I use Sonus pads, but recently bought 3M blue pads 3M recommended for their Perfect-it polish, not happy with the way the pad disintegrates in use! Equally, I've had the velcro backing for a Sonus pad fail after a few post-use washes, but have been able to replace it.
