Query: Suggested retail is WAY off targe

The retail on this is NOT $500.00. I found brand new ones for $359 at http://www.best-vacuum.com/dyson-DCO7steelyellow.htmlwith no sales tax!!!!! Not worth messing with a refurb. I've tried one of these at a friends, new, and after a month and it dealing with some fine dust from a little drywall sanding, you can hear a horrbile whining noise.. The hose is VERY bad design. It pulls REALLY hard and is difficult to use almost always pulling the vaccum over.
