A local Mac shop has used Macs like you wouldn't belive so I want to get a G3. I already talk to the store manager, and he can build a used G3 any way I want. Since I already have a hdd, cdrom, and ram he gave these prices for a striped down G3.

G3 Desktop Revision B300/266mhz-$60

G3 MiniTower Revision B 300/266mhz-$76

G3 B&W 400/450mhz-$150

Are these good prices? I wanted to get something for OS X just to play around with it to see how it is, right now I run a M$ free pc w/ Slackware Linux 10.0. So wich one would be best for me?
