I currently use a Vivi Nova with a 1.8Ohm head (purchased from GotVapes for about $15) on an ego style non VV 650mAh battery while I save up for a Provari and some genesis style atty's.
What I love about my setup is that it is super simple to get to work well. Right out of the box Ive only had 1 out of 5 atty heads not wick right and my current atty head is about 3 weeks old and still going strong. Flavor is good, Vapor production is good, and TH is good as well. The Nova is super easy to fill. Just unscrew the top and add
juice then screw the top back on. IMHO its a very newb friendly setup that is pretty much just fill and vape. Hope this helps
