Hey, do you know about those Fujitsu tablet PC's? They were selling them on ebay for like $800-$900. What so cool is they had fully reflective 10.4" touchscreens. The more sunlight on them the brighter they were. I was thinking it would be perfect for your install. You could make a whole CarPC out of one. Anyway, just thought you'd like to know. Hopefully reflective and transflective screens will be coming down in price soon.
