Just purchased a Mac Pro (2006) 3.0GHz 4-Core: 4GB RAM, 500GB HDD, SuperDrive, Bluetooth from OWC. The price of $275 was as good as most "buy-it-now" prices on ebay and OWC's warranty helps assure me of a good unit, which as we all know buying from ebay can be a real "crap shoot". But what really cinched the deal for me was shipping cost. In the past I've paid anywhere from $65 for MDD's to as high as $150 shipping for my quad G5 from California, so when I saw OWC's shipping cost to Canada I couldn't resist pressing the "Buy" button. As it says "PuroPost" is something new, I'm guessing to help encourage Cross-border sales. Anyhow, works for me. Now comes the waiting for delivery. Looking forward to upgrading and bringing this machine forward into this decade of the 21'st century.
