Really kick-ass sander. I used a loaner to sand part of a baseboard profile. Took me five minutes to do the room. Would have taken an hour or two to do by hand. That alone wouldn't justify buying it. It scrapes too though. Depends how much you think you'll use it. It's pretty specific use. Either scraping (I use multimaster or hand otherwise), or sanding profile (although it does have a flat pad, same size as RS400)
My dream package is RO 150, LS 130, RS 400. I'm only two away, one in hand, one on order, one in the future.
