Wife got me 2 of the Flatron L227WTG (LG 22) mentioned above this past Christmas. I love 'em.
I have the same one. Just bought it maybe 3 months ago at Sams Club for.. $250-270. Love it.I've got the Samsung Syncmaster 224BW. Have had it for about a year I think, and I've loved every second of it. Highly recommend it.
Go with a 24inch if you can, The extra screen space and 1900x1200 resolution kicks so much ass.
