What I really want (that's the major challenge) is the flip screen ability. I want something versatile not permanently a tablet, like the ModBook.

I have found used touchscreens for sale on eBay for around $60 or $70, which seemed much cheaper than Troll Touch. (Who didn't seem to support Lombards when I checked, either that or they were much more expensive than I thought they were going to be.) The thing I'm wondering about that is how to a) extend the cable between the motherboard and the inverter board and b) what other parts, if any, are needed to allow a touchscreen to be recognized?
