> there's http://dp2retina.rozsnyo.com/ http://dp2retina.rozsnyo.com/ which is more expensive but probably better I am aware of this one as well, but what qualities make it "better" than the Abusemark model I linked to? It's 3 times more expensive ($35 versus $99), uses 12V input (and thus cannot be USB powered), and has an 8-bit micro (ATxmega32A4U) instead of the 32-bit micro found on the Abusemark board (STM32F103CB). They both feature dual backlight drivers, although rozsnyo isn't listing what driver chips they're using, I suspect it's the same as Abusemark. The Abusemark firmware even provides a USB serial device in addition to firmware updates, which the rozsnyo lacks.
