Dell ultrasharp would be an excellent choice for a monitor.
Thanks everyone, guess I already had the right choice in mind.
I don't think you can go wrong with the 20" dell, but for an alternative, I'd suggest this:

I did a bunch of research. I narrowed it down to a dell or this, and after reading a bunch of review/blogs, I finally ordered the HP 2 days ago.
