build IR multitouch PANEL (for pc monitor)?

hello guys i am looking to build an infared multi touch panel, for my 15.6" lcd monitor.. i cant seem to be able to buy something in norma prices , at that dimensions anyway..

the thing is, i can only find, instructables for multitouch tables (wich use , a camera), but in my case, i need to build a panel , that will go above the sceen,.... anyone can point me at a direction where to search?? thanks!!

Not sure what price range you consider normal but here is a 15" IR touch screen overlay for $182.90


You will spend as much if not more trying to make one yourself.

i can as well find 15". i need 15.6"....
Is the added ~.2" per side really going to make that big of a difference? Even so you can use a 17" panel.
