Just a price note about Aspire coil heads for the Nautilus and Nautilus Mini (which is what I use): I get mine from Fasttech --
Authentic* BVC Clearomizer Replacement Coil Head (5-Pack) and order five packs at a time for additional discount, so the price at the moment comes to $6.97 (in US dollars) per pack of five -- or about $1.40 per coil head. Free shipping, though shipping takes a while -- maybe faster to NZ. That's versus 3.50€ per single coil head locally.
Important: Aspire doesn't allow buying with PayPal, and since that's all I use on Fasttech and similar sites, I figure out my total on any Aspire purchase, and buy myself a gift certificate from Fasttech [
link] and use the gift certificate to buy the coil heads (or whatever Aspire product). It's actually pretty non-painful, hardly takes longer than making my regular orders. The only thing is that gift certificates come in preset amounts, $10, $20 etc. But whatever extra is left over, you can apply toward another purchase. So if you bought 4 packs of five, the price per pack would be $7.16, for a total of $28.64, and you could buy a $30 gift certificate, and apply left over $1.36 on a future buy.
I'm only buying RTAs at this point, against the future possibility of being unable to buy premade coils at a reasonable price because of any EU regulations that might come down, but I'll keep using my Nautilus Minis until such a time comes. They're just really great, easy, reliable, no-fuss mouth to lung tanks.
