DS/RS 400 utility compared to RO90?

[footshooter5]

I have the DS400, RS400, and the RO90. I find myself more and more using the RO90 with the delta head attachment for those hard to reach areas and having trouble justifying keeping the DS or RS...anyone out there use either of those sanders with regularity? I should add that I also have the ETS150 and RO150 for larger panel sanding.

I use the DS400 all the time, on a daily basis, always painting houses and furniture and whatever that needs a colour. I also have the RS400, I use it less often but it comes in very handy for the places where the DS400 won't fit.

I used to have the RO90 and I like the sander, but I did not like the cost of its paper which is about 2,5 times as expensive as the paper for most of my other sanders, so it is not very cost effective. Add the fact that there was a lot of overlap from the RO90 with the 5 other sanders I had like the DS400, DX93 and RO150, and I made the decision to let it go.

But everybody does different things and has different needs. If the RO90 fits well in your workflow and the DS & RS400 don't, no need to keep 'em around. RS would be the first to go with me.

The RO90 definitely excels at corners and butt joint edges compared to the RTS400 (don't have the DTS so can't compare).  But there are plenty of times where the RTS is the right tool for the job, like edge sanding.  The body length of the RO90 is also such that it sometimes cannot fit into tight spaces to get at the edges and corners, so the RTS comes in handy then as well as a second best option. So overall I don't consider it redundant for my work.
