I've used many PC beasts in cabinet shops I've worked in, and at least for a time, they were the "go-to" belt sanders in the trade. My first own was a 4x24 Craftsman which lasted for years. During ownership, the ROS was invented and I made a slow transition from belt sanding to disk sanding (& threw out my vibrating sanders). But sometimes there are needs for a belt sander. The old, go-to PC beast, although dependable was (is) just too big & too heavy. Then I saw the (cough, cough) Black & Decker Dragster in a magazine tool comparison (forgot its rating, but it was high). After that, I bought one and am very happy I did. It is VERY light and its front wheel is 1" diameter (thus its name). The housing over the front wheel lifts up (like the hood of a car) which allows you to "plunge sand" (?), or get really close to corners! Did I tell you it's light and is easily controlable? A couple of years ago, the PC beast at a shop I worked with died, and with my recommendation, replaced it with the B&D. Everyone who used it liked it. Not only is it less than half the price of the PC, it does its job well and with half the effort. And if price is a consideration, that's only the icing on the cake!
Good luck with your decision.
