I have an acquaintance who is looking for a locally available, "reasonably" priced used Mac, something in the higher-speed CPU G4's (dual 800, 1.2 GHz or better) tower or iMac, or G5 iMac. He's looking to run FCP 4.5 or FC Ezpress and some audio apps. Not sure what his definition of "reasonable" is but I'll pass along any offers.
This would be used by him at and for a charitable organization, so there could be 501(c)3 advantages in play too. contact chuckr (at) mac dot com
