Amazon offers the La Crosse Technology Alpha Power Battery Charger, model no. BC700, for $29.99 with free shipping. That's the lowest total price we could find by $16, although it was a buck less in December. Sales tax is added where applicable. This charger supports NiCad and NiMH AA and AAA rechargeable batteries and features four modes: charge, discharge, recharge, and test.

Note that although it's out of stock, it can still be ordered at this price for delivery when available.
