Best advice is to go with corded tools verses battery. As soon as the revised model comes out the model you have is obsolete, and batteries may not be available. the only battery tool I have is a flashlight or drill. I don't have a 5" or 6" orbital sander. Of the portable sanders, I do have 4 detail sanders, 4 belt sanders, 4" and a 1/3 sheet square sander. In the last four years I only used my portable planer three times. Keep the videos coming.
