Also, Porter Cable made a rotary. The 7428. I don't know if they still make it or not.
UH...not exactly. The original poster didn't name a specific device...rather...was seeking something to "buff scratches and scuffs out with" in the very first post.
That can get accomplished with more than one specific device. People confuse naming devices buffers and polishers all the time...plenty of thread posts on that topic. You can buff/polish with either device, but a DA polisher actually does a better job with scratches & scuffs in most cases and uses a different design/technology.
By the way...
the Cable Porter 7428 is called a variable speed polisher, not a rotary buffer. Amazon carried it for a while:
Porter Cable 7428 Rotary Polisher
Unlike the 7428, the Porter Cable 7424 XP model is called a Random Orbit Buffer here on this site...
Porter Cable Random Order Buffer
...while most of the rest of the world calls that exact same model (including Porter Cable's site) a polisher like here:
Porter Cable Site Variable Speed Random Polisher
So when the folks selling them can't even agree on what they heck they call them...the public can certainly get confused as well. It's somewhat understandable, since they do more than one thing...depending on the user need.
