Well, I just went to H/D and picked up my Wen set and I must say, I'm impressed. I plugged it in and ran it both with the flex shaft and without. I don't see how it could be any better. I'm sorry that Steve Good's had some runout. Mine doesn't. Now, maybe after some use it will loosen up but that's to be expected I guess. I'm very happy and for $20, I don't see how you can go wrong.
