Titanium Disassembly, Worth It?

My girlfriend's grandfather's Titanium PB's display was broken, or something, apparently. The point is that assuming the only thing wrong is the display, would it be worth it to pop a new one in there for him?

I know the insane amount of work that has to be done (everything inside the computer has to come out, and I mean EVERYTHING), but its definately do-able for me work-wise.

Anyone have any suggestions where to find displays at? (I've only found one or two places so far)

I would probably do the whole $300 fix anything through apple stores.. it would probably be a lot cheaper as long as they would do it for you.

What is this fix anything you speak of?
