OK, SWMBO has just given her permission to buy a Festool C22 and a sander. Now I need to know from the "experts" here which sander would be best for my situation. I already have a RO 125. I'm planning on using the sander for finishing work on furniture. For that purpose am I better off getting a RS 2 or an ETS 150/3? Yes, I want to beat the April 1st price change.
