I am sure that a large operation like Auto Parts Train understands the marketplace, and has looked at the investment required for the parts it does stock, and decided where they would place their money.
Trust me, if Denny's guesses on the numbers are anywhere near accurate anyone in the business would be all over this market in a heartbeat. Look at it this way - if you had the expertise to make these things and knew that the only other place doing it was knocking down $350 an hour how long would it take you to jump into the market at a "discount" rate of $250 an hour?
IMO, the problem is a little more complicated than a couple guys sitting around BSing about it understand.
