I picked up a 12" Shop Fox bench top disc sander back in 2010. Price I believe was something like 225 at the time on clearance. Its been a great little sander all this time. Motor and disc wise, no issues at all, and I use the thing quite often. Dust collection is very good, and boy, you gotta use a collector. Cheap sandpaper performs like crap!!! If you do get one, spend a little on better paper. Youll be glad you did. Runs nice and quiet as well. The thing is a little tank. Nice and heavy, no vibration, no dancing around the bench top when its running. This particular design is pretty much a knock off of many of the others out there. Pretty much the same thing, just varying paint jobs. Table came with a miter guage and adjusts from around 40 degree's to 90.
The only complaint I've had is that the table can be a bit fussy as far as holding its settings. If you just let the weight of the wood rest on the table, she holds pretty well, but if you tend to press down while sanding, eventually the table slips out of adjustment. Clamping jigs to the table can be a bit tricky at times. More often than not, I take and use a piece of 1/2" ply and just screw the jig onto the plywood, then use the miter slot to hold the plywood in place.
There are no doubt, much better units available, however for the last 9 years the ShopFox has severed me well and for the money, I don't think you can beat it.

doesn't look like much of anything has changed with the unit over the last 9 years............
Great machine for smaller to small/medium sized pieces. You really kind of limited by the size of the table more than anything else. I've thrown together a larger platform to work off of from time to time and that does the trick.
