madvapes has both the 18650's and the rcr123's in stock.
I got my 18650's from MadVapes
I bought
this kit for my rcr123's from all-battery.com
And for what ever reason went with the wf-139
charger from BatteryJunction. I just like to match my chargers with my batteries.
I ordered my chuck on 2/11 and no news as of yet. Can't wait though. I have everything ready to rock as soon as it comes in.
