Tenth of the price, no way, at least in the states, unless maybe talking about the Chinese cheapos that they practically pay you to use. Thick aluminum plate does tend to be expensive, but the good plastic or composite pads cost as well. If you price it around you can stumble on some cheap aluminum stock. One outfit on the west coast is real cheap, but then there would be shipping. I think plate has applications where the plastic pads are less suitable, imo. Different kinds of aluminium plate affects price, and the stuff that machines well or comes looking pretty isn't needed. Might not go for 1", 3/4 or 7/8 would suffice, I believe. I've seen the plastic pads break, though deterioration from age may have been a factor. so far never metal. Weight is a downside,
