Anyone know where I can buy a preformer (new or used)?

Is it for cabs or facet stones? Separate machine for preforming or an attachment to an existing machine?

Graves makes one that can be adjusted to fit most machines.

Ideally, for both faceting and cabbing. Cheapest, I assume, is going to be an attachment to fit a cabbing machine. Are Graves still going?
