|HI Josep, |
You do not advise your location, which may help.
I may be wrong, but the ebay item you have found appears to be an add-on touch screen for a machine that does not already have a touch screen, and does not include the broken glass you refer to.
Also it is not cheap!
Suggest you further research to locate the correct spare you require.(maybe a broken unit for use as spares).
Have you checked with the Maker's website customer service? Here is their UK webpage:-
If only a glass panel is required, could one be made from a picture frame glass of the correct thickness?
Please advise back on progress.
Good Luck - Keep us posted.
