I've found vaporjunction.com for my HV 510s @ 4.5 ohm. I tried ikenvape's 3.5 ohm and it was just too hot, might be better at 5v. So my issue is this, at 6.95 per atomizer vaporjunction is the best price I've found so far. The $6 shipping, and the fact that they run out quite often is the issue I face often. Has anyone found 4.5ohm 510s anywhere else for decent price+shipping? I have searched where I can, saw some at indyvapor.com for $9 each, and as much as I love Drew and his drip tips nhaler.com's $11 per atty seems way too expensive. Any luck? Anyone else love that 6v 8watt sweet spot too?
