I wouldn't purchase a Grizzly lathe for one reason. The 1x12TPI
headstock they use. Rather then the more standard 1X8TPI or
1-1/4x8TPI.

I have one of the 1x12 headstocks, and have no problem getting chucks
and faceplates for it. *Sharing* chucks and headstocks is a different
story, and it's always interesting to set up for the craft fairs and
demos.

All else being equal, yeah, a 1x8 thread is preferred. That's also a
common pipe fitting, so if you're into making your own faceplates and
such, it's the way to go.
