theres no such thing as a plain lcd that plugs into anything you want if there was we'd all have one.
What are you talking about? There are plenty of LCDs that accept composite cables, which almost (if not all) video signals can be converted to. Finding one that is smaller than 2.4" (which wouldn't be very enjoyable to play, especially for long periods of time) that can be purchased from the internet or a retail outlet may prove to be difficult.
Back to the question at hand ....
If you're looking to take this on trips, your best option is to get the third party LCD screens that accept composite (RCA) connections. If you want be able to hear your game, get something with built-in speakers or a headphone jack. There are LCDs that don't attach to anything, they just sit on a little "kick stand". If your trips are going to be in a car, you can go the headrest monitor route. However, if cost is an issue, your best bet is to get a Hip Pad controller. They can be found for about the same cost as a MS Controller S.
As far as making the XBox smaller. You're not going to get much smaller, and even if you try, you'll end up spending more time and money than what it's worth. Just get a carrying case for your XBox to hold your games, controllers, and cords.
