I'm looking to buy a portable secondary LCD monitor for my Macbook Pro, does anything like that exist?

I found some laptops that provide a dual 15'' monitor solution (but it's already baked into the hardware). Also some ideas posted about creating this type of setup back in 2007.

I'm looking for something that is as thin as a laptop LCD (with maybe a bulky power supply that I could easily daisy chain or plug into a power strip along with my laptop).

How difficult would it be to buy a 17'' laptop screen and hook up a DVI connector and power supply, and build a simple monitor stand for it?

I've gotten to used to a dual-monitor setup at work and at home with my laptop that having to use my laptop in single-screen mode makes me feel crippled.

LD220G looks like just what I'm looking for (hopefully I can find a case for it to put in my laptop bag). – Dougnukem Nov 29 '09 at 17:41
