I have a Bissell Powerforce that I got at WalMart about three years ago. It's lightweight, easy to use and does a great job of picking up.
It's interesting to me to see how many people swear by Dyson. I used one in a daycare where I worked a few years ago and absolutely hated it. Maybe we had a "lemon" or perhaps it's just a personal preference thing.
