Get the Porter-Cable 7424. But change to the velcro backing plate by Meguiars and get velcro backed Meguiars pads. I use mine for polishing and removing paint problems and the final buff. I usually apply wax by hand.
www.coastaltool.com has it for $109.
The word on "Orbital" Buffer is that it is impossible to burn the paint. Rotary buffers are the paint burn culprit.
