I don't know anything about that P-C sander, but I do have 2 similar sanders. I bought a Ryobi at Home Depot for $80 when it was on sale a couple of years ago - regular price $120. It's pretty good for the price - plenty of power & has a dust collection port which is not great but better than nothing and very easy to change belts. I don't use it too often, but it's sure nice to have when I need it. I mostly use the belt, very seldom the disk - as someone noted, the miter guides on these inexpensive sanders are not very good.
I also have a Harbor Freight unit - regular price $75 but about $60 with a 20% off coupon. That's about all it's worth & I wouldn't recommend it for it's intended purpose at all. Much flimsier than the Ryobi, not easy to change belts, no D.C. port. However, I reversed the drive belt & use it to sharpen my tools. It's very good for that purpose - there's a tutorial in the IAP library on making the conversion.
I use a disk sander in a chuck on my headstock & a Rick Herrell jig in my tail stock to swuare up blanks on my lathe. Some folks have jigs to do the job on a BTBS, but I prefer to do that job on a lathe.
