With the Tiger release date set (woohoo!) it's time for me to upgrade, which means a great deal for you!
RAM: 256MB PC2700 SODIMM (used for less than a year without problem)
HD: 40GB Toshiba MK4025GAS (sealed, brand new warranty replacement from another Powerbook)
I figure that $30 obo for the RAM should be a good deal for the entry-level Powerbook owners out there and that for $70 obo someone can put the HD in an external Firewire case to hold backups, hours of DV footage, or that growing iTunes collection.
