Walmart offers the Black & Decker 16-volt Cordless Dust Buster, model no. CHV1410, for $29. (Amazon charges the same for Prime members; Target charges a few cents more.) Opt for in-store pickup to avoid the $4.97 shipping charge. That's $10 under our December mention, the lowest price we've seen, and a current low by $5. This hand vacuum features a rotating nozzle and crevice tool.
