I am still in my quest for the best sander, but looking to buy within the next week. I started to wonder if an edge sander would be better. It seems like an edge sander could do everything a belt/disc could do and more. Is there something I am missing? Anyone with a edge sander have things they can't do that a belt disc can do or vice versa? Any input would be great. I am noticing there is not a big price difference between the two, so not really a financial drawback.
