Well, I started with a PC and it was a great improvement over rubbing on a car by hand. Then I realized that correcting paint was a long and tiring process (especially using 6.5" pads) but I've since learned that 4" ones speed things up nicely. I progressed to a Makita and tried 8", 7.5" and 6.5" pads - LC and Edge too. The only time I was really comfortable was using 6.5"PFW with 1Z Intensiv Polish, other times just didn't feel that great. I can run a rotary, but I don't care to. I thought about this for over a year and decided to take a big step and sell my rotary and buy a Flex. I have NEVER regretted that decision. Every car I do with the Flex, the better I like it. I has the power to correct and a much larger margin of safety that you don't get with a pure rotary machine. I know, I've had a few "opps" taking paint right off a piece of trim. But, I was lucky that the 2 cars that I got careless with were beaters and had paint missing in other spots. I'm not saying don't get a rotary or in the OP's case - use the Dewalt, they are great tools if you take the time to learn them, respect the power, and enjoy using them. But if you want something that is IMHO the best of both - get the Flex.
