I have a PR roll crimper for the 10 ga in my opinion its a worse design compared to the BPI one even though most people seem to say the 4 pin PR one is a better design. I suppose if you have a 100 ton press that can hold the shell in place otherwise it just spins and spins. The BPI crimper works fine and requires very little force to get a decent roll crimp. I think the problem people run into with the BPI crimper is they are probably using a way too high rpm.

I think the most ideal setup would be to run a custom pulley and slow it down to 120 rpms +/-.
