@QMcKay I bought it from Jaycar Australia. It has been since discontinued.
This is the listing in the NZ Jaycar store http://www.jaycar.co.nz/productView.asp?ID=QM3748.
Amazon have a similar monitor http://www.amazon.com/MIMO-UM-710S-Powered-Swivel-Display/dp/B002RMPASG.
Any monitor will work. I picked this one as it is USB powered and plug & play - perfect for a laptop or small form factor PC.
