Thanks for all of the feedback! I'm certain I could handle a rebuildable, just not sure I want to fiddle with it yet. First, I've got an iTaste MVP 2. Will the resistance meter on that be sufficient to test an atomizer on something like the igo-l or do I need a separate meter before I dive down that path? I'm also looking at the lower dollar Cisco spec atomizers, do they all fit standard 510 drip tips? I'm also curious, maybe a dumb question, but I know the 510 is a standardized threading/size, what is 306? Is it a different standardized size or does it mean something else?
