The LCD I'm looking at is the LCD for the Blackberry Pearl 8100:

Found at many places but this one comes from random Chinese seller:
I'm seeing them for sale around $12 bucks but shipping is probably involved.
The digitizer:

This one is sold out but shouldn't be too hard to find a similar one.
Further details:
I haven't had any luck finding drivers or hacked drivers for the LCD.
Since it's an LCD used in a lot of phones I mostly find replacement parts instead of DIY projects.
I realize this is probably manufactured by another company and has a part and product number under that company but I haven't had much luck finding it yet.
The digitizer is the 'touch' part of a touch screen.
They're not always built together as a single item.
So you can overlay a digitizer over an lcd screen, install some drivers, calibrate it, and there you go.. touch screen.
For instance you can do so with an EEE PC to make it a touch screen as is fairly common: http://www.instructables.com/id/how_to_touchscreen_EEE_without_soldering_/
