Looking for a specific kind of monitor...Follow

Okay, I'll get straight to the point. Lately I've had an urge to set up a second screen so that I can play a game console while using the computer. However, I don't want to just set up a television, as I've also wanted a dual monitor setup for awhile. So, what I'm looking for is something that I can plug both my PC and my console into simultaneously, that allows me to switch between the inputs on the fly, preferably with the touch of a button. If at all possible a composite video input would be preferred so that I don't have to buy a component video cable for my PS2. Built-in speakers are also a must, since I don't have any other means of output for my console sound.

Something like this would be absolutely ideal. Unfortunately, I was hoping to spend less than $300.

I was also considering this one. However, it only has component video, and should I buy the cable I don't know if a single sound input would be sufficient (or reachable ).

Are there any other suggestions out there? Is what I want even feasible?

No offense, but you're not telling me if what I want to attempt is actually possible with the kind of set-up on that monitor. Which is kind of what I was looking for, here.

Ah, that second one is perfect, just what I was looking for.

Thanks.

EDIT: I guess I was wondering if it would be possible to do what that little box does with a monitor alone. I take it the answer to that is "no".

Well, for instance there's the first monitor that I linked in the OP, which has all of the inputs you could ever need... though I don't know if it has the capability to switch between them on the fly.
