i'm confused, you will pay $200 for a 300 watt device, but you don't want to blow clouds?
Under $200 there are tons of options! The Realux 200's, Isticks I can go on and on for days.
What features do you think you'd like to have? What sounds like something you'd enjoy?
I just picked up an Eleaf Istick Pico and a Theorum tank for $54. 75 watts, multiple temp control settings, and it's a great size with a replaceable battery!
There's the mini volt, 40 watts of goodness around the same price as the Pico, but an internal battery, that is limited.
The Realux 200 can run for days with the three 18650's in it, depending on how hard you push it. Can be found under $80 easily, BUT you need to buy two full sets of batteries, keeping them married, meaning you need to charge and discharge them all equally. Ad to that that I'm just not a fan of series mods, I'm out.
But narrow down what YOU think you want and we can help you better there.
