Before you pull the trigger on that rig Tex, let me muddy the waters a bit.
I got an eLeaf iStick 20, and 2 Anyvape Davide BDC tanks for about what you'll pay for the MVP 20.
I like these tanks because the come apart completely, and can use either the Kanger BDcoils or the Aspire BDC and BVcoils. The eLeaf I like because of its small pocketable size.
I got mine from VapeNW.com and I am very happy with the products, the shipping, and the price...
