I was just wondering what sorts of vacuums you guys have. We've always bought what I guess you'd call the "cheaper" versions, usually under $100, and the one we're currently on seems to be on the downslide. The Mrs. wants to get a "good" vacuum (she has her eyes on a Dyson), but we've just never spent that much on a vacuum cleaner before. I was curious what types of vacuums you guys have (or have had), and what you might recommend. Does anyone here own a Dyson, and if so, are they any good?
