I'm trying to cheat and find it on CL. IN the process I also spotted this G4 Cube for $100: http://myrtlebeach.craigslist.org/sys/2967739232.html

The MDD is a better Mac, but I usually see Cubes commanding more than their performance is worth.

EDIT: I give up on cheating and trying to find the listing. SC just has too many different areas to search and I'm way too lazy to use Google Maps. All I was willing to do is search "G4" in each of the computers sections. I should probably remember more SC geography from when I worked at T-Mobile and was on a team supporting former SunCom customers after we gobbled them up to get spectrum in North and South Carolina, and parts of Georgia.

I think you made a great choice, especially with the matching monitor.
