I also think that the sigelei mini is the nicest mod in that price range--a bit higher quality than the Vamo. It is small (it takes 18350 battery, but the 18490/50 extension caps will be available soon).
A lot of people like the eVic, but it's a bit temperamental. You have to be very careful with it.
Vamo is big and bulky; it works great when it works, not so great when is doesn't.
But then again, this is true about all of those mods.
Except the ProVari--Provari works as advertised 99.9% of the time, and if it doesn't, it comes with a full 1-year warranty. It's also more expensive (the mini 2.5 in basic silver satin costs $159 for the mod only--charger and batteries need to be purchaesed separately) and doesn't offer VW. What it does offer is peace of mind and stellar performance.
