I've been begging the hubs for one of these for a couple of years and seems like now I'm finally going to get one! Currently, you can snag a great deal on the Slim Cordless Dyson at Walmart.
The Dyson DC59 Slim Cordless Vacuum is just $189 (reg. $249) shipped.
Powered by Dyson digital motor V6. Dyson suction power without the hassle of the cord.
