Hi and welcome! You have opened a can of worms with your question. Everyone here has their favorites. Your best bet would be to read the threads under the APV sub-forum where people debate every device available.I'm not sure of any VV besides a Twist or Spinner that a Kanger will fit on without an adapter (I apologize in advance if I'm mistaken), but adapters aren't that expensive.
If you don't mind waiting, there is a sale going on for VAMOs: http://.........blogspot.com/2013/02/super-low-vamo-3328.html

The T3 works on the newest sigelei Zmax as well. It doesn't on the older ones. They enlarged the drip well on the newest models.
