I'm trying to get away from having the laptop and Oziexplorer open in the front of the truck by setting up a touchscreen with VGA connection to the laptop.

My question is this: has anyone experienced decay of the signal from the laptop to the touch screen monitor through adding a long cord? The laptop would live most happily behind the seat. But the touchscreen is probably going on a console up on the passenger side. I figure I'll need about 2 metres of cable between laptop and touch screen. Has anyone else tried this and had problems with signal decay?

While I'm on the subject, does anyone have any feedback on any of the following touchscreen units?

The 8" one sold on e-bay through Skypro Site Link for about $212 with postage

The http://www.rapserv.com.au/prod5656.htm for $400 (yikes!)

The nameless 8" unit sold via ubuydirect on ebay Site Linkfor $286 with postage.

Any advice greatly appreciated. I take that one wants 800 x 600 native resolution. And the bigger the viewing angles the better. Anything else?
