It's worth paying extra for U.S. Dell support
With Dell you have the option of upgrading your support to a higher level for $200 and you will always talk with someone in the U.S. I've had great customer service ever since I paid the extra $ for the support. I have used Dells for 10 years and been very satisfied. I hear the low end Dells don't last, so I only buy from the small business group...all my desktops are Optiplex and have lasted until I'm ready to upgrade and then some. I don't prefer the Dell laptops--although I have one that's 9 years old and still working well.
