Hi Roger,
That "commercial" moniker is a tough thing for me. I would say it is well built and should last me a lifetime, but I do not think I would call it commercial. I guess I think of commercial as something that would hold up to a lawn service crew using and abusing it. Not sure if it would take throwing around or abuse, but possibly. It is built in the US, which I like, and uses a metal control rod (no cables). The wheels are plastic to prevent rusting. There is an agitator, which is just a spring clip, but seems to work well. There are still quite a few parts that are plastic, but I guess that is to prevent rust. They do make this model with a stainless steel frame also, but that is probably overkill. Something else will break or wear out before the frame, but it does look nice. :2cents: The hopper size I think is perfect as any bigger would get too heavy to push up hill. It pushes and works nice. I think the $168 price was a fair value. Here are some pictures. Let me know if you want pictures of anything else and/ or a copy of the manual. The reviews on Amazon say it is a pain to put together, but it wasn't bad at all.
