thanks man .....I have only used the Porter Cable, but I love it. Mine got stolen by the movers when we moved into our new house.... I'm still pissed! I still have all my pads, they just got the buffer and the flex plates and the EDGE adapter.
It was a tank, I had it for 3 years and it still worked like it was new. A very nice tool that seems to last too!
I'm going to be replacing it this summer though. It sucks to bad to wax a car without it.
