I have a Jet 10-20. It definitely fits the bill of "smaller drum sander" yet it has plenty of power and good build quality. I wouldn't hesitate to recommend it. It will go thinner than you'll ever need for uke work, I routinely sand material that's approaching veneer thickness (for headplate veneers and other purposes). I do this right on the conveyor belt, no backer. Some other small sanders have travel stops that would prevent this, at least without a backer board. The 10" width is enough to sand a glued up back or soundboard for a tenor uke, or you can do wider pieces in multiple passes since it's cantilevered. If I had the space for a bigger sander I'd probably own one instead of this, but this thing is extremely convenient in a small crowded shop since I can just set it on my main workbench when I'm using it, or set it out of the way in storage when I'm not.
My only other real reference for a drum sander is the one a friend of mine owned until he recently moved and sold it - it was a gigantic dual drum machine that was a total powerhouse. And nearly the size of a small car. I thought I would hate every second of using a small machine after being used to that monster, but I was more than surprised with how nice this Jet is.
