As an 80-series user since the line was introduced, I'll second what TH0001 said about their products.
I have not used any of the Lake Country pads he's mentioned, but with the Meguiar's foam I've had great success. Since I don't really care for the W7000, I tended to use wool with M84.
The M66 is a very good one-step product, especially for those paints that seem to mar by just looking at them.
When my business did "auction cleanup" for dealers, they wanted a one step on and off product. It was under $30/gal worked quickly, looked good, and offered some protection. It can be applied by hand, orbital, DA, or rotary.
If I'm trying to get marks from under a doorhandle that I can't reach with a machine, this is the product I use. It's great for cleaning up jambs as well.
