I have been doing a bunch of sanding and finishing lately and I am tired of the extra time swapping between sanders or hand sanding corners. I have 50 cab doors to finish in the next week or so. I am looking for a suggestion if either of the rectangular orbital sanders below are worth it. I have an old black and decker, but it is loud and useless. I did a search for the two I am interested in, but did not find any discussion. I like the festool since it will work well with the other sanders I have, but I know the Mirka would be good too. The air options are nice, but I am about 4cfm short with my compressor. Opinions?
