I first ordered the Dell 9020 from a vendor that was not very good. Not my choice. I just went to the main Amazon page and clicked on Add to My Cart. That computer started to crash frequently; at one point crashing every 10 minutes. I talked to the service department, and they suggested two fixes: download a new OS and test one RAM card at a time. Neither worked, so I returned the computer.I then ordered the Dell 9020 from Blair Technology. What a change! Better packaged, better instructions, cleaner, and the computer worked just fine. The DVD drive was not operational, but I called Blair and they sent another drive. No fuss. That drive is now working fine.If you are going to order re-furbished, I suggest that you look into the vendor carefully. Look at their return policy and guarantees. Look up the company on the internet. I should have done that with the first vendor. The price of the Blair version was about $10 more, but avoiding the many hours that I spent testing and re-testing the first computer is worth much more than $10.I am now a happy owner of a Dell 9020.
