Query: One more disappointment

I have many tools. I probably enjoy tuning them and making them perform almost as much as making furniture. However, the Jet/Proformax 16/32 drum sander has continued to disappoint at every turn. These extensions are necessary to hope to achieve a smooth sanded surface, however they are clearly not sufficient. For $120 you get two metal shelves that with a great deal of fiddling, but no clear methodology, you can provide some crude, but much needed support on both sides of the sander. However, you now have an even more expensive sander that consumes very overpriced sandpaper rolls, and remains a huge challenge to smooth a panel. I keep trying to make this tool work well, but still find I can do a far better job with a hand plane or belt sander in much less time. Perhaps it is time to give up and sell the whole thing.
