Sigelei Zmax3 Telescope with a SmokTech v1 Pryex CartoTank. It is/was my first step away from eGo batteries and mega-cartos and (for me) was a good choice/balance as far as price/performance. I know that there are better mods, I know there are better carto-tanks, and I respect and admire the personal choices that others have made for themselves. This hobby/habit has so many alternatives and options, I think that it's great that we can all take our own journey of exploration and each arrive at a different place that "works best for us".
