What can I tell you. Electronics are expensive, and we get 5 days to do the conversion.
We pull the gas so we can get the sensors and wells in like the factory.
As far as the price goes, how does it rate to the raw materials that it take to make something. I don't know but I payed $5oo for a Glock the other day and as far as I can see it is some plastic and a little metal.
I also like to use the analogy about the cost of lets say a oil pres reg. block assembley on a CVHF compared to something along those lines in a Chevy 350 motor. There are many reasons why prices are different.
