Hey oso,
Tomorrow they will be restocked with sets and batteries. If you want, I would suggest to get an adapter for the cartomizers you have.
That would be a 510 batt to 808/901 cart adapter. I have one and use 808 carts with the eGo batt with the cone over the carto and works great.
Also, they will have the Auto batts 2/9/10 and I will get one in silver to try out.
Hope this was helpful!
