i prefer those that use AA or AAA batteries since those can be found anywhere. the local corner store will have these when they may or may not have the CR123A batteries. plus they are usually much cheaper and can be bought in bulk packs where the CR123A batteries usually only come one or two to a package.
both of my Streamlights use the same type charger and battery packs. that's what help me make the decision to spend $185 for the LDE Stinger. i now have multiiple chargers that work off AC power and DC power an several battery packs for them. i can charge them in the house or the vehicle.
