My turn to put in my 2 cents. For now I wont worry about e-cigs being banned. I will continue to order juice as I need it, an won't hoard stockpiles of anything. If they are banned I will assume that everything will be seized. No more carts, juice, atty's, batts, kits or any other accessories with the exception of chargers maybe.
If they are banned, that will be a total bummer, but there will be other ways of obtaining what you need. As long as there is a demand, there will be a supply somewhere. If I don't feel like going through the hassle that it might take to get supplies, I'll just go back to smoking analogs.
