I believe that by "Factory Re-certified", they mean re-furbished to original specs by the manufacturer...
It's killing me not to grab one, but as I said before, seeing so many being auctioned off on eBay gives me reason to pause. Then again, same thing happened when TigerDirect sold off their last aliquot of 3Com Audreys... folks bought them up at $89 each and tried turning a quick profit on eBay... which was a reason why I didn't buy one of those either.
I'd buy the Profile 4 at $499 regardless. That's my "magic" price break point on it. And I'll bet Tiger drops their price to that if supplies outlast demand. Oh lord, if they'd only drop the price on their Compaq Evo dual P4 Xeon 2.4 server... I'd grab it at $899. It's listed at $1,899 now. I've got a long wait on that one. Don't ask me to justify a "need" for that one. It's just a gut urge, like wanting a Ferrari or Porsche. ;)
