Display for MacBook Pro

Looking to purchase a new display, preferably larger than 21 inches, for my new MacBook Pro (the one that's not yet released but will be soon ). I have never owned my own display but use one at work.

My first thought is that I would only want an apple display. They are just so damn sexy. But after realizing all my money will be spent on the new laptop, I just cant afford to throw down $500+ on a display. However, without sounding superficial, while I want it to be reasonably priced, I also want to make sure it looks cool.

So here are my questions-
1. Which display should I buy? and Why
2. Where is the best place to buy?

Little more background info: I am a graphic designer and also do other color sensitive editing on my computer including touch up for photography/paintings.
