Query: Buyer Beware

I bought a $750 paper weight. After returning the first unit I bought, I turned the second unit on for a third time when I got an E04 error. I called tech support and they had me update the firmware. That did not help. At this point in time, the tech said there was nothing else he could do and that I had a big paper weight. That was it. Oh he did mention that I could restore my data by sending it to a data recovery firm. I have purchased many computer related products over the last 15 years and have worked with many more -- I work in the industry -- but I have never been so dissatisfied with a product as I have with this unit. Not to mention their unwillingness to help.
