http://www.datamem.com has 512 MB PC133 memory for the Mac (desktop) for $71.00. Don't knock Apple for add-ons when all you have to do is flip down the side of the computer and stick in more RAM. Also the datamem memory works fine with the new firmware.
I just have to point out that the G3 uses less power than the Pentium, so watt hours (WH) is not a good measure of battery life.
