Thanks Jonathan.I bought a Grex last August at SWAT from one of the vendors. Cost was $129. It works great!
My air compressor has a 60-gallon tank but a small air pump, so slow replenishment rate.
I have found that you need a good supply of air to keep up with air tools. Air tools are air hogs.
The mandrel on this one screws in. I've only used the one that came with it so far but have had no issue with it.

I think the PROS comes with an adapter screw that lets you attach the pads with a ROLOC. If I recall correctly, WoodTurners Wonders has (or used to have) a screw adapter that could be used on other brands (with same threads).
One nice thing about the GREX was the kit I saw for sale had some extension rods which would let you sand inside narrow turnings without getting the whole handle inside.
I've got a large enough compressor with 5 cfm @90 psi, but the noise of it running is over the top.
Not going to get one now, but maybe it'll be a Christmas present.....
