I love the Shark I bought. When we were living in two places, I needed a vacuum for our apartment. Bought a Shark on Woot for about $70. Way less than half price. It was a "scratch and dent demo". There were a couple scratches on the front bumper and everything else was spotless. Woot sells refurbs and scratch and dents all the time.

The Shark is very easy to maneuver, easy to empty and clean, the attachments make sense and will allow you to do almost anything. It's lightweight yet powerful and every disconnect is the push of a button. The hand held attachment for stairs and furniture actually spins the small brush inside, first time I've ever seen that and it's very effective. Best vacuum I've owned next to my old-school Kirby.
