I had the 22-44, now the 16-32. Long story. Great machine if used for what it was intended to be used for. And that is not thickness sanding. That's what thickness planers are all about. It is also not a finish sander, as Allen points out. The best result I have with the thing is to sand boards before final cutting. In other words, cut to rough sizes, then sand to 120, usually taking no more than 1/16" total both sides. The other really great used is to band saw thin boards and sand smooth. 80 grit for that job, rough cut to size and then sand to 120 grit. The process saves me tons of time, especially when I was doing this for a living. Now that is not necessarily the goal. The other benefit was to finish at a thickness that accommodated joinery, i.e., 3/4" wide dadoes. Often 4/4 wood came in at 13/16". When I prepped this way I had actual 3/4" thick wood and joinery went much better. So I think of this machine as a pre-prep, rather than a finisher. Just my 2 centavos.
