When Jim Benn was producing the units (prior to selling the company to Mec), he sold units for Mec, P/W and Spolar. The P/W-Spolar unit was identical, but had different mounting holes on the platform as I recall. Mec had linkage that ran up the backside, where as the P/W-Spolar unit was more direct drive with a coupling arrangement.
I had Mec/Automate and P/W Automate units. Both worked well. I currently have the P/W 800+ and Spolar hydraulic. I use the shell feeder P/W sells, and like the foot control aspect. I just drop in a wad and watch the stations.
TOM: Yes I do. They are $799 and $849, the latter having the foot switch.
Incidentally, the Spolar uses a different coupler. I know because when Jim Benn was making the P/W unit, I made a coupler that would adapt to the Spolar. Jim then manufactured the plates with different mounting holes for the Spolar.
