I bought the ETS 125 and I do not like it. It is the perfect size that I need and the wight it great. Also no problems with dust collection. I love everything about it, except for its performance. It is not aggressive enough. I was thinking about returning it and getting the ETS 150/5, but I am unsure because of its size. I sand mostly raw woods (Oak, Maple, Walnut) and a variety of sizes, from small rail and stiles to table tops. So, I am looking for versatility in a sander. I already have a RO90, which handles alot of the small detail stuff I need, but I am lacking a good versatile ROS and am not quite sure another RO is what I need. What do you all of you think?
