All look like good. I personal don't like monitors with speakers built in. They just serve no purpose or break in 2 weeks. For about $200 I would recommend either Sammy or LG. I loved my LG Flatronic. The only real weakness was they don't give you a DVI cable (which is still Bullshit LG). Cool, brightness, quality had no equal IMO. I almost want my monitor back

LG 23" Wide
Sammy 23" wide
Otherwise, get the Hanns-G
