Welcome cappy! Just got my hands on a Provari and it's better than I expected (and the fanboys here have you expecting quite a bit out of this thing). Good choice on quitting analogs. I know all about going on a spending spree, but, if you can afford it, it's the best way to figure out what you like and what you don't versus what others tell you. You'll (hopefully) reach a point where you have the device and atty you like and enough juice to last you a stretch without having to spend until the next juice order - it'll happen..
By the way, always have a spare 510 atty (or whatever connection it is that you use). For one, it's really the most pure way to sample a flavor and determine the good and bad of a juice before you drop it into a tank. If something tastes awful or needs a few days to steep, it's better to know that after 6 or 7 drops than dropping 2.8ml in a ViVi nova you're going to have to dump out. There's also a point that many a vaper I've read (myself, included) reach where your favorite atty system (clearo, carto, tank, etc) just stops working as it should or you get an awful burnt hit and you can't find a way to fix it (the nova recently broke my heart this way). You want to throw in the towel out of frustration and then you reach for your trusty dripping atty, take a few puffs and you're good to go. I'd keep two around at all times and you don't have to get a $22 HH.357 or a $50 AVA. Just an $8 atty will do fine.
Good luck.
