OctoPI touch screen options?

I currently have a RAMPS 1.4, MOSFET, RPI and power supply crammed into my Maker Select's original control box and boy are things getting crowded.

I'm thinking it'd be nice to replace the RepRap display with one dedicated to octoprint, mounted somewhere outside of the main electronic enclosure, such as in front of the printer.

What are some cheap, compatible capacitive touchscreen options as well as ideas for a stand/electronic enclosure?
