I just picked up the
Timber by Element Mods (it's the big brother of the Droplet Mod Cman pointed out above), and I'm loving it! It's a 26650 and a bit of a beast, but the battery life is very impressive. Surprisingly, it's not too big for me to take out and about, either. They also have it in brass, which they've named the
Bonfire. I got the
Elm XL atty to go with it, which runs hybrid so it connects directly to the battery without a 510 connector and there's not much voltage drop. One thing I really like about the atty is there's a removable top cap, so I don't need to take the whole top off to drip. I also like the slits they used for air holes instead of the small holes a lot of them use that may need to be drilled out to work right. The Timber and Bonfire are interchangeable, so I think my next purchase will be one of those so I can have a mix of SS and brass. Here are a couple pics of my new toy:
There are many options out there, so I'm sure you'll find the "right" setup for you. FWIW, I'm a big fan of VapeRev for higher-end stuff. They're my local B&M and the folks there really know their stuff (and no, I don't work there; I've just been treated very well).
Good luck on your quest!
