Has anyone had any experience with the Shark Navigator Liftaway vacuum?

Ever since I saw a post on here about a user’s fantastic experience with a Dyson I’ve wanted to get one. Well, there is an infomercial on about this vacuum that is comparing itself to Dyson, which is always a ‘ding ding!’ for me…anytime something new compares itself to to something well established and proven good, well…anyway, does anyone have any experience with this vacuum?
