JemJem offers the refurbished 5.5-lb. Apple MacBook Pro Intel Core 2 Duo 2.8GHz 15.4" LED-Backlit Laptop with Case, model no. MB986LL/A, for $598.99 with free shipping. That's the lowest total price we could find for a refurb by $158, although we saw a refurb without the case for $9 less in March. It features an Intel Core 2 Duo 2.8GHz dual-core processor, 15.4" 1440x900 LED-backlit display, 4GB RAM, 500GB hard drive, SuperDrive, NVIDIA GeForce 9600M GT 512MB graphics, AirPort Extreme (802.11n wireless), Bluetooth 2.1 + EDR, Gigabit Ethernet, iSight webcam, and OS X 10.6 Snow Leopard. Deal ends June 9.

A 90-day JemJem warranty applies. Note that while this is listed as having a 1280x800 native resolution, it's actually 1440x900.
