You'll be pleased to know that we have decided on the screens.
As mentioned earlier - the key rings from Dick Smith here
And also some 8 inch photoframes also from DS here
Dick did us a sweet deal.
These ones were preferable to others due to their amazingly bright LED display. We also looked at portable DVD players, but decided against them due to their lame TFT displays....and who uses DVDs anyway? Everyone should get an HDMI box for projecting or displaying non interactive video!!
