I was planning on buying an RO150, as I have found several occassions lately where I want to level out the slight ridges in wide glueups where the joint is. I am an impatient sander so I usually go with my ROS and it can take a while, and I don't trust myself with a Belt Sander. This had me looking at the RO150, but after thinking about it and doing some research, I think this will probably be my go to sander for most things and am now thinking that the smaller RO125 might be a little less cumbersome for all around work. Just wanted to get some input on what others who own these sanders might think.
