Oh that thought definitely crossed my mind, and I saw that black model and you got the prices right.
Thing is, I've been vaping for a year now and have never tried vaping on TC, and I know that DNA chips hit the sweet spot for a lot of TC vapers.
Main reason is because my iPV D3 doesn't do SS TC, so I never bothered.
Maybe I'll tinker with TC in the future, maybe not.
I usually vape from 17W all the way up to 65W (which kills my single LG HG2 almost instantly on the D3), so dual 18650s would be hella useful moving forward.
My options now are as below:
a) Smok H-Priv + 4 Sony VTC4s for RM220 shipped from GearBest
b) Therion (~RM350) from auctions + 2 LG HG2s (RM40) from alexng
c) Wait for eVic VTC Dual
d) Get a Pico for RM100 and stick to my simple pocket friendly vaping style and build coils that fire 45W and below
While deciding and vaping on my dying iPV D3, I'm also waiting to see all the mods manufacturers are squeezing out their supply chain before the end of 8/8.
My my.. It looks classy af with the goon.

Looks like you already have your mind set which to choose though LOL. Now I'm waiting LV to open more option battery door to purchase. So I can swap different battery door depend on my mood.
