I get my tank replacement cartos directly from Smoktech here:
SmokTek Cartomizers - Boge single-coil and SmokTech standard or low resistance XXXL Dual-Coils!
I happen to prefer the single coil XL cartos to the dual coils. I was getting too much burnt taste with the dual coils and decided to try the single coils after reading some posts here on ECF. I own about a dozen cartotanks, from Smoktech DCT to Triple V pyrex to OCD pyrex and a Bella-Phiniac hybrid tank I mated up. I switched all the dual coil cartos for single coils. Since then I've not had any burnt taste, get the same great flavor and vapor, and noticed a moderate increase in the battery life between charges. I believe dual coils are over-rated in my own experience.
The above link will direct you to Smoktech where you can buy either single or dual coil tank carto replacements. These come in ohm choices of 1.25, 1.75, 2.0, 2.5, and 3.0 and pre-drilled 1, 2, or 3 holes. Previously I've gotten both 1 and 2 holes pre-drilled, using 1 hole for thinner juices and the 2 hole for thicker juices. You likely won't need 3 holes unless you are using Boba's Bounty or another all-vg juice.
I just received three new pyrex tanks from OCD
IBTanked Home
These tanks are the perfect size for a Provari and dirt cheap at under $25 each per tank. Easy way to put each of your favorite flavors in their own tank, including cinnamon or acidic flavors known to destroy plastic tubes. The XL size pyrex tubes will take your Smoktech XL tank cartos if you continue to use them. The standard size tube takes standard or regular Boge size cartos. Tubes are available clear or in high quality painted style. Three styles of stainless steel caps or acrylic caps in several colors.

click pics to enlarge detail. First two pics are the OCD pyrex tanks, third pic is the Bella-Phiniac hybrid tank I matched up.
I also highly recommend getting the Slap-yo-Moma tank accessory tool from
Slap Yo' Mama Adapter : Big Daddy Vapor This tool will protect your o-rings from the cartomizer's sharp edges and decrease assembly and filling time of your tank. There are other tools from other sites but this one is hands down the best and I even own the rest.
