Got tired of waiting on the K2 Kit from SF so I going to pull the trigger on these. Saw them on the Quartermaster public safety catalog I just received. Kit is $24.99 (2 LiFePO4 RCR123A batteries, up to 1000 charges, Charging cradle optimizes battery perfomance, AC/DC charging plugs) and 4 pack Batteries $14.99. Shows as new item on the catalog and first time I've seen it. Is this a good deal? Thanks!
