Max VGA resolution

K lemme make this simple. I got and über PC. I got a few über screens. But I'm missing and über tablet. Now I was thinking about getting a Cintiq 21UX, but the price made me think again (like that's nearly two 2560*1600 monitors wtf). So I happened to come across a DIY guide on making a DIY Cintiq. Good news - it's cheap (running low on cash). Bad news - I'm not wrecking one of my monitors. So I happen to notice a monitor for like under $200 with a decent resolution of 2048*1152. The problem is it's only got VGA, no DVI or HDMI. So anyone know whether the screen will be blurred or crisp like DVI?

And if anyone knows a cheap screen with over 1920*1200 (2.3MP I believe) you can gimme a link if it won't kill you.

My max is 1920*1200 (default at 1620*1050), but it wasn't under 200. I believe you will notice a little degradation if you are accustomed to a HDMI input.
