Amazon Warehouse Deals offers the used Dell UltraSharp U3011 30" IPS LCD Monitor for $854.08 with free shipping. That's $136 under last week's mention of a new one and $254 under the lowest total price we could find for a new unit today. Features include a 2560x1600 native resolution, 7ms response time, 370 cd/m² brightness, media card reader, five USB 2.0 ports, two HDMI inputs, and more.

No warranty is included, but Amazon's 30-day return policy applies.
