I bought the TS55 and CT22 last month and was so impressed with the tools that I looking to get a sander or two now. Yes I am already addicted. [big grin] The main use of the sander is for finish sanding. I currently have a 5" Dewalt ROS and that has worked OK up until now but I am looking for something better now. I am looking at the ETS150/3 for a general sander and a DTS 400 EQ for getting into the corners on assembled projects. Does this make sense? I see that there are a lot of option when it comes to sandpaper. What should I start with for sandpaper? As I said the sander will be for finish work. Right now I am finishing a project made from Cherry plywood and solid cherry that is finished with a wash coat of shellac, cherry stain (to darken it a little) and several coats of poly. Later I would like to get a Rotex but that looks like more sander then I need right now and for the price of that I can get these two sanders to start with.
