I just got myself a DA G4/466 with 384 megs 'o RAM for $20. Came with the original box and packaging, which is always nifty to get Got it to set up for a friend as her first experience with the Mac
Sweet score, and a great starter Mac for a newbie. You can put a decent version of OS X on there, and the CPU options are great too. I scored a dual 533 CPU for $70 from olde-mac-milt
Verily. Or even an oldbie. I'm posting from what was a DA G4/466MHz/384MB only 8 weeks ago, but is now 733MHz/1GB, dual boots 10.2.8/10.4.11, and drives a 20-in ADC LCD display. It has taken over entirely from two 500MHz CRT iMacs as my workhorse(s), and has the screen real estate to be useful for sound and text editing.
