Years ago an old friend, Dave came over to my shop. He had brought along his new Craftsman router along with a tall straight cutter. He said that he was routing a groove in a piece of wood running against a straight edge and the cut came out uneven, not straight like you would expect. He tried the cut several times, each with the same result. He concluded that either the cutter was defective or the machine was. He asked if I could test both. I chucked the bit in one of my routers and duplicated his cut. The cut was fine. Next we checked the router spindle with a dial indicator. It was way out of wack. Dave said no problem as the router was only a couple of weeks old. He had bought it when Sears had their big annual Pre-Xmas sale. You know the one where the ads say 50% off. Get our top of the line router or whatever tool for half off. Well Dave took the router back and explained what was wrong. The salesman took the router and briefly looked at it. "One of the sale ones I see" he says. Dave asked him how he knew as he had't told him that he bought it on sale. The salesman told him that he could tell by the serial number. He also told him that although advertised as "same as" there was no way that this was true. The only thing that was the same was the exterior case, all the guts, bearings etc were of lesser quality. I've never bought a Sears tool since that episode.
