The Interact Mobile Monitor for the PS1 seems to be a good (cheaper) solution from what others on this board have experienced. Do a search and you'll find some info and someone just posted pictures of it in action I think. It goes for $150 retail, less on Ebay. I beleive its a 5" screen. Just make sure you avoid the round case - its an earlier version and apparently sucked. If you look around the web for reviews I recall someone said that DVDs looked "great" on it.
