Once upon a time, I attended a convention where they tracked the cost of a $100 dollar list price back to the initial cost. At no step on the way was anyone gouging or inflating the price - and the initial cost was about $13 dollars!
It was an eye opener.
We all want to get paid for our labor and investments, so your $20 dollar CO2 cartridge would be about $125 to be added to the list price.
Of course, try and buy a mid range saw today, the 300-500 dollar field only has jobsite saws, the basic table saws are gone.
