I saw this on ebay. Bally Alpha touch screen and touch sensor for curve monitor, with new sensor board. Brand new unopened. $159.00 Vendor claims to have 10 of them.

It was unopened. I peeled the plastic film covering from the glass and installed it on my monitor. It worked like a charm. This seems like a good deal if you would like to replace your scratched or chipped glass.
