MegaMacs still offers the used Apple MacBook Core Duo 1.83GHz 13" Widescreen Notebook, model no. MA254LL/A, for $379.99 plus around $20 for shipping. That's the lowest total price we could find for a system with at least this much RAM by $199, although we saw it for $2 less in July (since expired). It features an Intel Core Duo 1.83GHz dual-core processor, 13.3" widescreen LCD, 1GB RAM (more than standard), 60GB hard drive, DVD/CD-RW combo drive, 802.11g wireless, Bluetooth, and more.

A 30-day MegaMacs warranty applies.
