1920x1200 Monitor

[Kos13]

So it looks like I can get up to 2048x1536 resolution, but I guess 1920x1200 is the biggest flat panel available for anything less than a 30". Assuming I don't mind paying a few extra bucks to get the perfect monitor for me, what should I shoot for? I will probably play as many tables as my screen allows, and I play on different sites with different screen resolutions, so that's not a make-or-break factor for me.

It looks like I can get the Dell 2707WFP for $700 (http://beskas.com/product_info.php?products_id=1858). Is the extra size worth the difference in price between that and, say, a 24" Acer (at Best Buy for $400). Also, is there really any difference between a Dell/Samsung monitor and a cheaper monitor like Acer/Westinghouse? Most of the Dell/Samsung monitors appear to be a couple hundred more than the cheaper brands.
