Found this for 149 online, but store sold at 169. Used heavily for a few weeks, but little to no overload. It gathered shredding at teeth, blocking insertion of new paper. Then a clunk and no shredding. Our mechanic opened it and lo and behold, a gear was sheared, BUT there was a loose gear rolling around inside that exactly matched the broken gear. He installed and it worked again better than ever for about half a bucket. The teeth gathered shredding, there was another clunk, but no additional gears in the box. I hope to get warranty protection, but we'll see.
