This D buring tool is very good for PVC pipe. It takes a few tries to get the hang of it, but then you can start using it really quickly. I've had this guy for many years.
Great product for copper and even PVC, can be larger in diameter for a better grip in the hand and the handle has room for more spare tips. I think for the price it will last a long time.
Pros
Deburring tool with pockets for quick deburring of edges, pipes and sheet metal.
I've always been a fan of rothenberger plumbing tools. The tool is still made in Germany where quality still counts, not some inferior Chinese junk. Quality sometimes costs a little more, but is worth every penny for applications such as medical gas instillation.
