That might be true and if so, it just backs up what I said. The old saying, "buy the best and cry only once" still holds true. Especially if you are going to make your living with it. Do try that fix though. It does sound like after much use, the tension rod has pulled the sliding wedge too many times and has worn the slot so the rod needs to be shortened up to take out the slack. It's not a hard adjustment. Also, there is a spot on the cover plate that requires filing down to relieve it so the rod can't hit the plate. Again, not a hard fix. As long as the saw still saws, there are things that can be done to prolong the inevitable.
