BuyDig offers the LG 29" 21:9 Ultrawide IPS LED-Backlit LCD Monitor, model no. 29UM58-P, for $209.99 with free shipping. That's the best price we could find by $30. It features a 2560x1080 native resolution and two HDMI inputs.

Update: Specs corrected - as a reader pointed out, it actually has two HDMI inputs (rather than one).
