Bests & Worsts Reviews from Amazon

I bought this sander for $500 from Woodcraft for my guitar shop. When I got it home, I unpacked it and was quite pleased by the apparent quality of the machine. It sanded quite well, and the sanding belt was very easy to change. Also, the overload protection worked flawlessly. However, no matter what I did, the belt would not track properly. I called Performax, and they sent me a new conveyor belt (twice), but still, it tracked hard left. This is a problem because eventually the belt eats itself from going off the side of the rollers and jams into a bracket under the table. I took the sander back to woodcraft for repair (they were very cool about this), and they could not get it to track properly either. This has apparently been a problem with the 16-32 as well. Well, to make a long story short, Performax told them it would be 1-2 months for a replacement part or unit. After a month at Woodcraft (who apparently replaced one of the rollers), they gave it back and the darn thing STILL will not track properly. No matter how I adjust the rollers, it always tracks to the left!!! I'm VERY disappointed here- after years of hearing how great Jet and Performax are (they're all owned by WMH tool group), I thought I'd have no problems. Oh well- maybe it doesn't pay to go with the name....I realize that this unit is made in the far east, but I'd hope that Performax wouldn't put it's good name and valuable reputation on such a piece of junk!
