I never realized how expensive those little screens were. For those prices, you could get a nice big screen tv in your house.
An idea I'm thinking of doing, is buying one or two of those 15" LCD monitors for a computer, and then splicing them up to a dvd player (well, it's not as easy as simply splicing it, but it's not too difficult with the right knowledge)
I think you can pickup those monitors for under $300 each.
