I'm looking to upgrade to a mod with a smoother output than my itaste 134. So far I've come across the sigelei 20W, Vamo, and Lavatube. Any input on other options I'm missing? I'm running Cerotank with 1.6ohm BVC and Hygeia clearomizers. I figure I don't need more than 20W. I like the SX200 chip but a mod with buttons or dials for wattage adjustment is preferable. I know everyone prefers box mods these days but I like how my old Nemesis feels in my hand. The 134 is just too big for pockets. The Nemesis was the right size.
