I'm going to buy a Jetbeam RRT-0 R5 soon, and want to buy a couple AW RCR123 batteries and a charger to go with it. What charger should I use for the batteries? I have done a search and read through some threads, but I just want to be sure I'm going to buy somewhere that works and is safe. I would prefer to buy the batteries and charger at the same place, and I also would rather not have to do any modifying on the charger to get it to work(i.e. ultrafire charger+RCR123).
