The Hcigar VT200 and Efusion are both decent choices. I have the Lavabox, it's an okay mod but 900mah and 1a max charge so probably wouldn't be a good choice for your needs. I've also got the Cloudmaker Whiteout DNA on pre-order https://vapourdepot.com/product/temp-control/cloudmaker-whiteout-dna/ There's been a few delays but production has finally got underway so hopefully only 2-3 more weeks of waiting. Love the modular approach and how so many things about it can be changed, appeals to the PC builder in me. Also has the option to replace the Lipo with a dual 18650 battery sled and after using the Lavabox I think I'd be happy to trade the 67w for the extra battery life. The Reuleaux looks awesome and surprisingly not that big for a triple 18650 mod. PBusardo ha sit in his device round up in part 3 of his DNA200 review.
