Touch screen monitor...cheep cheep

Instead of using some crapped out software to provide a user intrface,
I've decided to use the runtime screens with in Modicon PL7 software to enable it as an HMI. What is the cheepest/best touch screen PC monitor that you've used?

I have not used their touchscreen, but I do like the rest of their HMI products.
