Clutch Resurfacer - Boninfante

Just curious if anyone has any experience/thoughts one way or the other about the portable Boninfante VF-750 clutch resurface machine versus the Van Norman FG4000R portable clutch resurface machine?

We have the VN, but a guy that we know is looking at the VF-750 for his use due to $$$. We've never used the VF-750 machine, and would be curious about any feedback.

Thanks.

 

It works decently, does a good job(for being portable and non-coolant running) on the steels. I don't recommend using an actual grinder on clutch discs though.
