I owned very briefly the Rigid R2611 which I intended to use for two projects I had at the time: sanding drywall and portions of a large window frame I was refinishing. It was tough to get my CT Mini hose to stay on it with an adapter. I tryed it on the window and I was done trying that in 2 minutes. Why? the weight. I looked up the weight and I could swear it was listed as just under 9 lbs but I guess I was wrong I just looked at your thread and it says 6lbs allthough Home Depot lists it as 6.3lbs.
I ended up doing every inch of the walls in my living room with a ETS 150/3 which weighs in at 4lbs and was a joy to use on that job as well as wood.
Currently I am trying my RO 150 ( 5lbs by the way ) on some wall work and allthough it is a little more cumbersome as compaired to the ETS 150 I wanted to see how it would do because I need to have something more aggressive for removing some paint in another room that has flat over semi gloss :
I was pondering the Bosch 1250 as well before I bought the RO 150 but they didn't have them in stock yet at Lowe's so I couldn't see if the dust collection port would be compatable with my Mini. This sander does look like it could be a viable alternative to the RO 150 if you don't mind giving up a few IMHO Big pluses with the RO150.
1. the edge protector which allows you to get right up to a adjoining surface without damaging your sanding disc or the machines pad.
2. The center hole in the disc which pushes (using air) the sanding dust out from the center to the outer vacuum holes. This makes your paper last longer as well as less mess.
3. Festool abrasives: I also recommend Seth's choices for grits and types. Ive used Brilliant 2 for striping paint off wood shelves and if you regulate your speed setting so you don't build up too much heat and melt the paint the disc stays clean and lasts for a long time. ;D
Oops I guess I was a little long winded there :-\
