This is a fairly new product, the Ultron Snap Change has been around for
several years at least. I've seen the Ultron setup. Uses special holders
and a drawbar setup. There is a centrifugal mechanism up top that will
not allow a release if the spindle is turning. If this mechanism fails,
oops....
The Acu-Rite setup is essentially the same thing, except they use a full
length R8 adapter with their pull stud in the end. I talked to an
Acu-Rite rep about this. He stated they wouldn't sell the pull studs, as
they needed to insure concentricity of the stud to the holder. Might be
true, might be BS to make more $$.

I think the Acu-Rite setup would be a bit more rigid, but requires more
clearance to change tools. In either case, you have a bit of work cut
out for you should you need to fit a right angle head, or some use some
R8 tooling that cannot be had with the pull studs.
