I'm sure this is asked often but I have a 2009 Macbook Pro and am considering getting an external monitor (between 21 and 24 inches) for the laptop. I initially considered selling my current MBP then getting a new iMac and buying an old Macbook just for portable use but realize I use my laptop on the go a lot more than I'd use a desktop. But I still wouldn't mind having a big monitor for home use/gaming. I've seen a few Samsung and ASUS monitors on NewEgg. Any thoughts? Note - While Apple Cinema displays are awesome I can't justify that much money for a monitor.
