NC_Girl - You can get a touchscreen LCD. Worst case, if you don't like it, you still have a bigger second monitor for your laptop.

I don't know the differences between the technologies. You want something that claims to support multitouch though. The cheapest monitor on the list is a 21.5" from HP that has that capability.
I don't know if that's the best price, but it should be a pretty good selection.
