MegaMacs offers the used Apple 24" LED Cinema Display HD Widescreen LCD Monitor, model no. MB382LL/A, for $689.99 plus around $25 for shipping. That's the lowest total price we could find for this now-discontinued display, although we saw a refurb for $116 less last summer. It features a native resolution of 1920x1200, 1,000:1 contrast ratio, 330 cd/m² brightness, 14ms grey-to-grey response time, built-in iSight camera, 3-port USB 2.0 hub, and Mini DisplayPort connectivity. Offer ends April 25.

Note: A 30-day MegaMacs warranty applies.
