AvalancheSJ, it's still worth shopping around for a cheap G4 as you should be able to find one in your price bracket if you hunt. The FSB does make a fair bit of difference and the CPU is in a different league. Don't forget the slot loading iMac's are unupgradeable and really struggle with stuff like flash. The tray loaders were cpu upgradeable to a G4 but they had rubbish graphics Rage II/Pro. The G3 iMac, unless it is for the most basic of stuff is a bit long in the tooth for many things now.
