Good input, thanks.Can't say I'm surprised to see the $200ish increase over the steel version. That hardware kit alone, is at least 4x the size of what comes with the original. Plus, welding components into a complete piece is a more cost efficient option, than machining the ability for the components to be bolted together.
I'm just chiming in because I was expecting a higher price. Usually, the aluminum causes about a 50% increase over the price of the steel versions.
