Display options for live Amiga use?

[RedWarrior]

Hey guys- I'm considering my options for reviving some Amiga hardware for on-stage use. One of the main concerns is the need for a small but reliable display that would either connect to the RGB port, or just the composite port (if it's the cheaper option)... I saw this very cheap display for the Raspberry Pi: http://www.banggood.com/3_5-Inch-320-X-480-TFT-LCD-Display-Touch-Board-For-Raspberry-Pi-2-Model-B-RPI-B-p-1023432.html

Is there something in a similar price range that would connect to an Amiga 500/600/1200?

Thanks for any useful input! =)
