Sorry: 'for a "one off" project' (i.e., a "one time buy")

Yeah, pricey. As I said, I figure I can get "everything" in
a "used" PDA for considerably less. If this was a full prodcuction
run, then I could afford to "buy new". :-/

The first thing that came to mind was a replacement screen
for the touch-half of a Nintendo DS from DealExtreme.
Something like these two pieces?

That may still leave too much yet to be done.

So, what's your question, then? Get that PDA, cannibalize it and you're
done...

Excellent! Yes. I assume the two are assembled together
(sandwich) in the Nintendo? I.e., I would have to mechanically
mount them atop each other.

I will look into the DS and see what it's capabilities are
as well as what the likely interface would entail.

Thanks!
