In general, just about any monitor should work in your situation. It's best to walk into a store and check out one monitors to see which one you like, then look online for the best price.
My general purpose monitor is the Asus VK246H 'cause it was cheap at the time I bought it. It's only used about 10 - 15 hours per month. The VW246H ($220 at Newegg.com) is cheaper since it does not have the built-in webcam, otherwise it is the same monitor.
I wrote an indepth review of the Asus VK246H; you can do a simple search for it.
