Okay, I asked this in what I thought was the right forum, but nobody's responded yet, so I'll try here. The title says it all. I'd prefer copper batteries and atomizers, manual or auto, doesn't matter, but preferably both. White or green LED if possible, but not necessary. I'm trying to find the best deal on batteries and atomizers because I just ordered a 510 kit last night, and I know in time I'll need spare parts. I want to know who's the most reliable and cheapest for supplying them.
