I find the LS130 indispensable when refinishing cabinetry, I don't have the 150/3 maybe it takes me a couple extra minutes to run up a grit or 2 higher?
I find my 2 LS130s a bit frustrating to use. I'm doing a lot of reno work. Whilst they can be useful for mouldings on skirting, architraves et al I find that the papers clog prematurely. As soon as the paper even starts to accumulate paint residues the abrasive performance drops to almost zero. I still have to scrape almost all finishes away first through a combination of Skarsten & Sandvik scrapers, heat gun and elbow grease.
Despite having twin counter rotating balancing cams the Duplex sander is also pretty vibratory. It probably has the highest level of vibration of all my sanders, and can really only be comfortably used for limited periods of time. It's not just the amplitude but also the frequency of the vibes that's the issue.
The RO90 can also be a handful at times. Its delta performance isn't as smooth, rapid or easily handled as my dedicated Deltex or Bosch Blue sanders. In rotary mode it can be difficult to control, being a bit "top heavy", especially in comparison to my little Metabo SXE400s (I have 4), which are a lesson in smoothness & ergonomic soundness in comparison. Obviously the RO90 is much, much faster in Rotary mode, but for overall quality of finish the little 80mm Metabos are superior. Plus the SXE400s, the Deltex and the Bosch GDA280E are also much more compact & ergonomically sound, which is really important in furniture restoration jobs. These 3 abovementioned sanders are specialists, whereas the RO90 is more of a generalist, being really 3 sanders in one (for the price of 3 or 4).
There's no such thing as the perfect sander. Each of mine has specific strengths & weaknesses, and perform particular tasks accordingly.
I also use 5" variable speed grinders with backing plates and carborundum discs where dust isn't an issue, or even an old Triton 5" Random Orbit grinder attachment where speed is required. Grinders will actually outperform my RO150 in non critical jobs such as weatherboards. The combination of speed (6-10,000 rpm) and aggressive grits (24g) makes paint stripping a breeze sometimes: when the disc loads up with paint residue, the heat generated smoothly degrades and abrades multiple paint layers without harming the substrate.
The only sanders I don't have any use for are standard orbitals, having disposed of mine years ago. A combination of Rotary, Random Orbit, Linear and Delta Orbital actions covers just about all my requirements these days. My belt sanders are just about permanently parked on the shelf too: the others do their job so much more smoothly, albeit slower.
