Hey,
Does anybody know what the cheapest 7" LCD Display is?
I won't be using it for anything special but just for like a
LCD Button Box thing
Its like you can press the button on the touchscreen and it like shows an image of a Button Box like Ignition Etc.. And it will interact like switch engine on..

I've seen a few things about connecting your Nintendo DS to your computer as another Monitor or using Wi-Fi connection,
I've got a Nintendo DS and that would be a cheaper option.

Or would it be cheaped to buy a Button Box for my computer.. Although I'm not prepared to Solder or anything like that.

I would just like a button box with a USB-Cable and some software, Then plug and play!

Thanks,
Tisy0

I got one of ebay for about 90 quid,

I use it with TouchBuddy that allows you to do exactly what you require
