Wow thank you for all the quick replies. It's given me a lot to think about.
First off I live in Minnesota.
A fellow gopher, so I can give some local (if you're living in the Cities) advice.
I decided to quit smoking in April. I looked at gear online and got thoroughly confused. So I decided to buy stuff from a real local vape shop. I checked out Yelp review (yeah, I know, Yelp--take it with a grain of salt) and went to Smokeless Smoking in Nordeast. They set me up with an iStick 30, a Nautilus, and a bottle of Nick's Blissful Brews Smoked Custard. I ended up paying more than I would have by ordering online, but I got immediate satisfaction instead of waiting for stuff to be shipped and instructions for how to do things like fill the tank (trickier than it looks at first) and prime the coils.
I've added a couple of tanks, but still just use the iStick. A charge lasts about a day. The Nautilus is still my main tank, but I play around with some others.
I've been to a couple of vape shops to try things out or pick up some small bottles of juice to try different flavors, but I like Smokeless Smoking the best, even though it is probably the most expensive. I like that it does not give off the head shop vibe that a lot of places have. I'm 50, and my days of thinking psychedelic black light posters and carved onyx pipes are cool are behind me.
So I'd recommend a trip to a local vape shop--SS is my favorite--and be prepared to spend 20-30 more than you would ordering online for your first rig. After you have been doing it for a while, you can quickly move up to the fun(?) (yeah, it IS fun!) of ordering no-name clones from Fasttech and big bottles of cheap juice online.
