I have a friend looking to make his own hardware portable setup, however he has a very specific spec on the screen. I figured this is the best place to ask. He needs:

10" diagonal
1366x768 resolution
susceptible to frontlighting as opposed to backlighting - more like the GBASP than a PSP for example.


He's hoping to find a source where he could get one for less than $1000, one source quoted him $4k which is beyond his prototyping budget. Anyone have any ideas?
