No, I don't know of any other vape stores other than the one on Old LaGrange. My current setup is a Kanger 1000 mah with a Pro Tank II at 1.8 ohms. I have two of the batteries, one is a 1308 and one is a 1309. I don't know what the difference is other than the 1309 being about a half inch longer; I'd love to know if there is any other difference between the two. I'm dying to get a variable mod but my budget now is close to nil.
