Well I have owned the Bosch ROS20VSC 5" 2.5AMP for a few years and I found it to be pretty darn weak, and needed something stronger so just a few weeks ago got the DeWalt DWE6423K 3.0AMP and it's noticeably better at stock removal using the same Mirka abrasives. The DeWalt is surprisingly well made. Low vibrations, doesn't chatter, and works well at dust removal with the included bag. I can't figure out a way to hook it up to my current tiny Rigid shop vac so I haven't.

I'm new to Festool. I realize, like routers, one sander is not going to be enough. I have my eyes on an ETS EC 150/5 to complement the Pro 5 down the road...
