i've been looking into a new monitor as well. i'm leading towards the "BenQ E2200HD" or the "BenQ G2220HD".
i've skipped over these: (and a few more)
New monitor
BenQ G2220HD 22-inch LCD monitor - Reviews - Hardware - Monitors - LCD Monitors - PC World
BenQ E2200HD 22in LCD Monitor Review - Monitor Reviews - TrustedReviews
E2200HD has hdmi port and speakers, and doesn't cost that much more but it in reality it's just some gimmicks that i'll probably never use.
choosing hardware is so finicky ~_~ i'll probs be happy with what ever i end up getting though D:
post what monitor you end up choosing and a small review :> (i'll probably do the same)
