I have the RCBS case prep center but anymore I only use it for removing primer crimps and to uniform the primer pocket.
I use a Possum Hollow trimmer in a power adapter, as well as a chamfer/deburr tool also in a power adapter. It's a great deal faster than using the prep center for chamfer and deburr.
The case prep is ok for primer pocket work, but there are other tools available, and if I were to do it all over again, I would not get the case prep center, it's too expensive for what it does compared to other tools and it's slower to use.
