I'm in the EXACT same position as you. In the span of 3 months of vaping I've gone from a Halo Triton 650mah starter kit, to the Vision Spinner 1300mah with Kanger MT3 tank and, because the Vision battery maxes out at 4.8 Volts, I'm just not getting enough and looking to get an APS VV/VW device.
I've been researching these Mods for literally weeks and watched reviews for the Joyetech eVic, SID, Lavatube (not flush and no drip or recess channel so it limits the tanks you can use), all the Zmax units, all the Innokin units like the Itaste 134 (too monstrous and tacky), the MVP Pro 2.0 (Watts don't go high enough), and on and on. And with each one, I find something that seems to be a deal breaker. The eVic is too weak and limiting. The DNA-20 devices are too much power and don't offer a more low-end vape. Some devices don't have button lock and each touch changes settings...there's always something.
I like the SID and the Vamo the best so far...but haven't found that one that says, "Yes! This is IT"
