I am looking into possibly getting another sander. I have an RO 125 and a bosch random orbit. I have been looking into the ETS 125 and RS 2. I was thinking the ETS 125 because the papers would be the same as my Rotex. I've heard the ETS 150 is a lot smoother but the price is a good bit higher. I like my Rotex. I do mostly hobby work and my projects so far are end tables, cocktail tables and similar scale so it isn't like I am sanding huge pieces. That may make my want of an RS 2 seem odd but I would think it would be good for final sanding before staining on the top to get it nice and flat. I am assuming I could also use it on poly to get the final sanding with high grits, is that correct? So far, my sanding on poly has been limited to hand sanding with sand paper and synthetic steel wool. I am not very familiar with power sanding on poly.
