For us, we color-sand all new paint to 5000 grit, -and on old paint rejuvenation, we color-sand by hand to 2500 grit and follow-up with 3000 grit on a Hutchins DA before doing the buff. We use a compound called Perfect-it with a PorterCable random orbital buffer and a foam pad. The issue with using the older heavy-duty buffers with a wool pad and heavy-duty compound is you can overheat the paint and it also creates chatter marks in the surface that you just worked so hard at blocksanding to make straight.
The bottom line is you are using a media (either sandpaper or buffing compound) to level the surface. Therefore choosing the correct buffer for your application depends on how nice you want the finish and which method of prep work you plan to do before polishing.

Like Brent I use the PorterCable. However it has a big heavy handle that gets in the way sometimes. In this
video (click video) I show how I solved the problem very cheaply.
