Ok, 1 dollar is a little high, but honestly i'm not sure what they plan on selling it for?
The Jeep Haynes Repair Manual has an older style one similar to this, and I know several folks out there have been looking for one:
A clear/tinted, Polycarbonate, jeep hard top.
Jeep magazine has been working with the company "The Lid" to get a better product set up for delivery. Keep an eye out for these guys!
