I have a DX-93 which I purchased to use primarily in refinishing woodwork trim in my old house. Much faster than my little Proxon (like a miniature Fein Multi-Master) and much easier to control than my Bosch Vario (narrow belt sander), and great for sanding contours, inside corners and the edges of trim pieces that are very close to a corner. It would be a better tool if Plug-It were added, and if motor housing were smaller so it wouldn't interfere in tight areas, and if the speed control included a tachometer - mine hunts for speed no matter the setting on the dial and no matter whether under load or free-wheeling in air. But it does the job and is easy to control. Very useful for getting into corners, recesses and rebates. A near perfect complement to a Rotex sander if you are refinishing a staircase. I also have an RO 125 and an LS 130 in addition to Bosch 1/4 sheet pad and 4x24 and Vario belt sanders and a Milwaukee 1/2 sheet pad size orbital sander. If I had to cut back to two sanders, the DX would be one that I would keep.
