This post reminds me of when I purchased my first PC machine. I had been using those big red buffers you can buy at Sears with those cloth pads that stretched over the edge of the machine. I never got very good results with that unit so when I bought the PC I thought I was in detailing nurvana. Since that first PC, I've added a second one along with a Flex 3401 and recently my first Makita rotary, which has allowed me to properly handle most any correction I run into. Still love my PCs though.
