5.0 inch TFT screen with arduino due

Hi Guys

I am planning on ordering this screen and shield to try it out with my Arduino Due and Henning Karlsens libraries.

Before I order it I was just wondering if anyone knows of an alternative 5.0 inch touch screen that only uses 8 data bits. I am hoping that if all goes well I can use this screen on a system I have set up using a Due, but I am very short on I/O so saving the 8 would be huge for me.
