There are some cheapies out there now, like the eLeaf iKonn 220, Yosta Livepor 160, Boxer Rader, and Tesla WYE. The eLeaf resembles the Alien, the Yosta is shaped like an aspire Archon, and the final two are in the Minikin 2 shape without touch screen. Not sure if any are decent.
Voo Poo Drag gets great reviews but all those hard edges.
Real world selling prices for the Squid 2.1 are also coming down.
My only Smok mods are a Koopor Plus and both sizes of V8 sticks.
Kaos seems more reliable than other recent Sigelei, but is not light, and lacks vent holes. Mine has a little fire button rattle but it does perform in wattage mode.
