This guy ships worldwide. This monitor is SVGA 1024x768. Is it in your price range? Or is this still too much? Shipping from Miami might be the killer. Not sure what is reasonable to you. If I were seriously looking to start a project like this, I would probably pick this up. In my experience at trying to pick up single used monitors on eBay auctions, they would start out in the $10 range and by the end of the auction end up in this price range anyway. Otherwise you'll end up putting off the project until you happen upon one at a second hand shop.

You're right about the LCDs, I have yet to find a reasonably priced SVGA 8.4" 4:3 (i.e under $200) anywhere. And I still have yet to devise a method to put a flat screen LCD in the case that looks like it belongs. It's certainly a bit easier on the Color Classics as a piece of Plexiglas, curved over the LCD makes it look authentic. The older models are a bit more trouble since it has to curve around all four sides, but in each case that rules out touch screens – not that I could afford that kind of luxury in this kind of project presently. And as anyone knows about me, I'm not a big fan of altering the case. Besides, altering the case for a flat screen throws the aesthetic off: they were never designed for it, though one could make an argument for the SE, based on prototypes and the Portable designs.
