I just bought a used eMachine M2350 with the following specs:
Windows XP pro // Longhorn
15.4" widescreen UXGA
1.5Ghz AMD 2800 Athlon -M
60GB HDD
512mb DDR
ATi -M 9000 32mb
CD-RW/DVD combo
3.3 hours of battery life (uning minimal power setting)
Broadcom 802.11b/g internal card
(4) USB 2.0 ports
USB Floppy
I paid $950 for it and it's still under warranty and runs better then my old Compaq 2590.
