Best Buy offers the Dell 24" 1080p LED-Backlit LCD Monitor, model no. E2414HM, for $99.99 with free shipping. (Newegg and Office Depot and OfficeMax charge the same.) That's tied with our mention from a week ago and the lowest total price we could find by $29. (Most retailers charge $149 or more.) It features a 1920x1080 (1080p) native resolution and DVI and VGA inputs.
Update: It now costs a buck less at Microsoft Store.
