I am looking for a powered sander, not having used one for 40 years, and rarely then. I am now building a few projects and while currently at the rough carpentry level, I can see that, if I continue, hand sanding will be a pain. I want a high quality sander with good dust collection that can also be used for both buffing and, perhaps less often, in aggressive mode. I have examined and handled, but not used, most of the Festool sanders and feel that the Rotex 150 is just a bit big, and, at UK prices, more money than I currently want to spend. While all of the above might pretty clearly point to the Rotex 125 (???), I would like an opinion on how the Rotex 125 compares with others in the Festool line-up as regards sanding performance.
