I am no expert on this but I went through the polisher/buffer debate last year. I ended up buying the Porter Cable 7424 polisher and it is very good for compounding & polishing (yes the lake country pads will fit on the PC with the correct backing plate). I used the 3m 3 step process (compound, polish, wax).
It is is difficult to screw up any finish with the PC due to the design; if you apply too much pressure the pad will slow or stop. I mark my pads on top to get a visual on how the pad is rotating.
When it came to waxing & buffing.. I apply the wax by hand and use a variable speed rotating buffer (borrowed from a friend) with a 3M super Buff pad to really bring out the shine. IMO the Porter Cable is not real good at buffing.. I plan on buying a Variable speed buffer this winter.
