This is really cheap if you think about it... By the time you buy a 4.3 touch LCD screen, LCD controller, Graphics controller, PCB + extras. Then write all the code / library's to make it work, you will be a couple hundred in.(Your time isn't free)
We use it for robotics and it is a really nice display with the new Visi-Genie. We used the display before w/o the Visi-Genie and it was a lot of code to make it work. (3+ weeks) With the new software we had the interface designed and implemented in a few hours. :)
