VapeNW is a good place for tanks I found! Another to keep tabs on would EvapeUS. Just ordered a second Cool Fire Plus 70w mod as well as the Freemax Starre Pro having tried the first Starre model out. Made up a new cover for one of the social networks with a fast look at how the collection of mods appears presently while you are not able to see the 10w iStick mini or second 40w model with temp control when rounding them all up!
As you can see it's mostly the Atlantis tanks V1 and V2 Mega with only a few higher wattage capable tanks being the Freemax and Sense models for handling 50w or more while having several 50w, one 60w MVP, Luxyoun 150w wooden box, the SMOK BEC Pro on the far right next to the first Cool Fire IV 40w and 70w models with the Clouper ZNA 50 where the first Atlantis tank has a problem with part of the 510 threading and I had to bring the contact pin all the way after it went on the first time! I put the original Atlantis model on afterwards!

Out of the 6 tanks ordered on separate occasions only that one gets tight about 1/2 way in!
The main task again however at this time is the wait for more tanks to appear that do actually handle the 50-70w thrown at them while the 100w or 120w max will see about 70-80w in actual use depending on the ejuice you toss in! That's another element I run into at times especially for anything containing menthol! The non menthol flavors usually take the higher wattages.
If you look on the top row right next to the Vamo Fire with the outer wood body you will notice the Dovpo E-LVT 30w mod which was the first thing I thought at the time I could run a sub ohm tank on. Actually the Innokin iTaste VTR will run one as well but only at the 15w max! which is the last on the top row without any tank by the way.
The Dovpo was what I ordered from FT on 11/18 and didn't see that in until 12/26/14 28 days later! That went for $53 and was marked down quit a bit when it got discontinued which is not any surprise.
$35.92 E-LVT 2.0 7-30W Variable Wattage APV Mod - brown / power bank / LED flashlight at FastTech - Worldwide Free Shipping
The flashlight on that as well as the ICIG V9 50 also seen next to the Luxyoun 150w in the center top was another with a useless flashlight option that didn't last more then a couple of days!
