I'd pay $70 for an aluminum Sig 213 body with no TC and a reliable, efficient chip. 150w, fires down to 0.05ohm and a 2 amp charger.I agree about Kanger , good tanks but mod's , no thanks . Never had a Smoke but had a Cloupor and the chipset is terrible , turns on/off randomly etc...
You are right about sigelei and P4U 's ipv series , used to be much more solid but unfortunately they have also gone down the cheaper is more profitable than quality path .
All these manufacturers are in a wattage/features war. No one cares about efficiency at all. Or quality.
I knew ipv stopped caring when they left out the final firmware update for the 3LI. Stainless/custom TCR.
No one really makes VW mods anymore. You have to pay for broken TC so they could list that as a feature.
The cheapest most powerful device I know of is the Tesla Invader line but no TC and no charging.
You're asking alot out of $50.
