I'm in a similar situation in trying to figure out which sanders I should buy. I am in need for the following jobs:
1) refinishing big oak front door (pics in another post)
2) 23 stairs, umpteen million spindles, and a railing (pics in another post)
3) 3 old wooden storms
4) some of my wife's old furniture when she was a kid that my son is going to get (all wood)
5) some panel doors from my house
6) any new projects with bare wood
7) any more refinishing
All of these items will be chemically stripped as I plan on staining them (except for the wooden storms). I was originally thinking RO 150 but have some hesitation as to whether I really need it or just want it. Other options are the the RO 125 and 150/5. Or, I could keep my Bosch ROS but am concerned about dust collection as the treads on the stairs will be done in the house and would like to do the other stuff in the basement. I do plan on getting the DX 93 for sure.
Sorry to hijack the thread but I thought my post was reasonably pertinent.
