My initial set-up cost has been quite expensive to get what I wanted compared to analogs, however in a few months it shouldnt cost me pennies a day compared to the $4 a pack a day I was spending on analogs. I just ordered a Kayfun, a couple more AW batteries and an extra charger, along with my juice stash I should be set until 2015.
My downfall is also being able to shop online so much cheaper than my local B&M store. At least Im off the analogs!
