More often I have customers asking for where they can find a suitable touch screen monitor that they can use with VisualTouch.
Through some research we found the LG L1510SF model and ordered a model. After a week of using I can for sure recommend this monitor. It works very well with VisualTouch.
The screen uses USB for its touch screen communication (instead of some other models that still use RS232) and is reasonably priced.
