I purchased one of these for my home office having learned long ago that consumer grade electronics (Inspiron line for Dell) don't offer the reliability and longevity I need for business use.  I had a bad experience buying directly from Dell 3 years ago when the computer arrived dead out of the box and customer service was a nightmare.  I figured a refurbished unit would at least have been tested.  The computer is exactly as advertised, works perfectly and is cosmetically indistinguishable from brand new.  The cost for the configuration I chose was about $500 (or 1/3) less than the unit would have cost from Dell.  I could not be happier with the purchase and would not hesitate to buy from this vendor again.
