I want to do some video editing of mostly home movies, along with the regular stuff like itunes, surfing, office, etc. and have thought of buying a 20" iMac new for $1500. But I am wondering if my 1500 isnt better spent going on eBay and trying to snag a G5 Pro for around 1500.. I also like the idea of the G5 Power Mac as I can bring my own monitor and not stuck with iMacs stand mounted monitor. Upgrading the graphics card and HD is also possible. So I see some advanatages to going a used computer over a new one but don't know it well enough to decide. Not even sure if I could get one at that price.. Your thoughts and advise are most welcome and appreciated.
