A little sumptin-sumptin to think on...
When I got my sander, I felt that the infeed/outfeed was a bit ackward. Lacking support. SO I took a couple of 2x2x28" (or something like that), purchased a couple full pull 24" ball bearing drawer extension and 2 rollers. Made up a couple infeed/outfeed rollers that I can extend and retract at will. This has worked very, very well, especially on longer boarders.
