I have a 18 bit sharp LQ10D421. 350 nit. Comes with an ERG inverter, a hyperion controller, the hirose (but you'd have to troubleshoot it), and everything else you'd need. I'd need about $220 to recoup what I have in it though.
No touchscreen though. But the other I have has a digitalww overlay that works great, but it's going in the dash.
Speaking of, I also have Sharp LQ104V1Dg11, 18-bit, 350 nit. Brand new backlight inverter and Capacitive Datalux touchscreen. I'd trade it for an 18 bit 8" screen w/ touchscreen.
