History is shaped by our hands.

Okay, Mindsay pals... I have a question for you.
I'm buying a new computer sometime in the next 2 weeks. The one I want is an Apple dual-processor G5 that costs $2500. However, I can get the exact same computer for $500 less if I get it refurbished.
Apple, of course, claims that their refurbished products are just as good as new ones... and they do have the full warranty. But I'm still a little leery.
Does anyone have any comments on refurbished products? If its an Apple refurbished item, that would be even better, but overall I'm just curious. $500 is a LOT of money. Heck, its 20% off.
Also, please don't debate Mac vs. PC... I don't want to get into that here. I'm buying an Apple, that's all there is to it. Please just give me your thoughts on refurbished products.
Thanks, all.
