Vintage valve-grinding machines...

[Special Coupe Frank]

For several years, I've had a hankering to get a valve grinding machine ( an older one).

Cruising eBay and Craigslist, I've mostly found Sioux, Black & Decker, and Kwik-Way.

Assuming a given machine is complete and all motors functional, is there a particular make that's more practical these days, in terms of finding replacement wheels, etc ?

Thanks...
