@staceybritt13 - I'd recommend Rocky Mountain Vapor and/or Desert Vapes, too, that were linked to above. It's hard to beat RMV's 30% off code sitewide and his free S/H with $14 and up total purchase. Desert Vapes is a great site IMO, too, and Tish (the owner) is very helpful in the event you need help sourcing things. She also gave me an on-going 10% off coupon code to pass along to friends. If you'll PM me, I'll give it to you.
As far as other tanks for your little iStick Mini 10W mod - I like to use the little Aspire K1 tank (takes the Aspire BVC coil), as well as the Protank Mini 2 and Protank Mini 3 tanks...(they take KangerTech really inexpensive and still readily available coils). Those are all eGo threaded tanks, but an inexpensive 510/eGo adapter works with all of them on a 510 threaded mod like the Mini 10W.
BTW - If I were you, I'd avoid DHGate like the plague! It took me 2+ months to finally get $300+ back...for 13 hard to find tanks that a DHGate seller
never had, and could
not get...yet they'd listed 500 in stock and available, when I'd bought and paid for them! It required 2 long unsuccessful Chat Sessions with their customer service reps, numerous messages back/forth with the "seller", and
finally reporting them to my Credit Card company (required my sending 28 pages of documentation - copy of the listing on DHGate, their Customer Guarantee policies, pages of saved Chat Sessions, all the saved messages with seller, etc.)...to
finally get my money refunded to me!
