Get this Black & Decker 14.4V Cordless DustBuster (model CHV1410L) for $49.99 at Woot. Shipping adds $5, but even with that, this was still the lowest price we found by $15. It runs on a rechargeable lithium-ion battery and has a rotating, slim nozzle and brush and crevice tools. Sales tax is not charged in most states.
