ETC does not manufacture Monitors of any sort, much less the touch screen kind. You can purchase an approved monitor and use it with the console.
There is a list of approved monitors somewhere that I will work on
tracking down for you, but I can't seem to find it right now.
By the by, The touchscreen support is standard on the ION. It's not a feature that you have to pay extra for - it comes with every ION.
Also - In the post about -it should be DVI connector, not CVI. Do be aware, that the two monitors that are currently (or at least were) being used to display your Expression outputs will more than likely not work for the ION. You will need to have at least one of them become a DVI monitor. A DVI to VGA
adapter on the cable will not work as the
desk only supports DVI signal out of the DVI output.
Let me know if you have any other questions.
