I bought the festool rotex sander too and my god what a difference. That thing, although a fun challenge to control, is probably as close to an industrial machine with a hand held tool as I have used when it comes to sanding. It ripped through the router marks and scorch marks using 60 grit, 80 grit then switched the gear to eccentric motion for 120 and 180 grit. I was done both sides within the hour. Cut the time into 1 quarter in comparison to the festool orbital and still just as even. Very very impressed with it. According to my merchant, it is by far his best seller and I know know why.
