I have had a used PD for about two summers and 20,000 miles. This was with the 6lb pulley. I ran 110.6 mph at the strip showing about 4-5lbs of boost. I finally broke the internal belt about 2 wks ago. I found a supplier for the belts and bearings. I rebuilt it in about two hours. It was a piece of cake.
If you buy one, IT WILL BREAK THE BELT, just a matter of time. BUT, I can rebuild mine a lot of times for the differerence in price.
If I was to go new. I would go Vortec, but with the deals on used Powerdynes you get a lot of bang for the buck.
