I'd make one out of plywood and drywall screws before I caved in to that kind of gouging. Gimme a break.

I don't blame you for your sentiment but I have done business with Mike in the past, sold him my Carbon fiber Supertank, and he's a good guy, and a businessman. But he's really not gouging anyone especially if someone decides it's worth $750.00 to them. If no buys, then he has to look at them setting there or offer them at a lower price. I could not see me ever paying that much for a set either, but as I have said in other posts, I can't believe some people would pay 3-4 hundred dollars for chrome plated plastic side covers, but some did! At least the lights perform another function other than just reflecting light. ( Bladedog, not busting your chops about this, just offering another viewpoint. )
Back to the original post, I have been on my Valk since 99 and was just able to snag a new still in the package Cobra lightbar this past summer right off this forums classified section from a guy in California. It was all just chance and luck as I must have seen his post within 5 minutes of his placing the ad. Got them for $250 plus shipping which was fair given the availability. So just keep looking and hope to be first in line when an opportunity comes along.
