[linux-audio-user] (OT) to buy a touch screen

Hi all,
I think that some of you have already make a "kiosk" with some
interactive sound apps running on.

It is the first time that I try to make it, my problem (in this 1° step)
is to find a on-line seller (in europe) in order to buy a kit for a
add-on touchscreen (i need only the touch panel, I have alredy the
display).
Someone can spoint me to a place where to buy (in Europe) this kind of
things ?
Thanks for whichever aid
