I recently picked up a Wallstreet G3 300 MHz with 192 MB of RAM and a 4 GB HD with the 20x CD-ROM drive, OS X Jaguar, Office X, etc, and the power cable, minus the battery for 100. Was this a good deal? Anyone know of some good 3rd party batteries under 100 new? What should I upgrade, I know I wanna upgrade the HD and the RAM, but is there anything else I should look into? I really REALLY love this machine.
