I bought a DA polisher from Harbor Freight today. It is the model with the serial number ending with 29 which is supposed to be the most like the old Chicago Electric. It was half as much as the Porter Cable at $59. I used the money I saved to buy a Chemical Guys 5 inch backing plate and 5.5 inch pads. If needed, I will change the grease. I also found a nice tool bag with pockets big enough to carry extra pads and polish.
