I've been using a pro tank 2 and mini pro tank 2 and need something else. Lately it's been inconstant taste and I seem to be burning through atomizers at a high rate. I'll look into those issue but for this thread I'd like alternatives to tanks, except I am open to hearing about carto tanks. I haven't tried cartos and am open to it. I'm not into rebuildables but if there are atomizers that have a little capacity to them that have heads you can buy I'd be open to that too. Or anything else really. Just need to find something before I do nuts.
