I've been vaping for almost 1 1/2 years and I'm still keeping it simple. I have a collection of batteries (spinners being my favorite at this point) and carto tanks and cartos. I've had a few vivi nova's, but prefer carto tanks. I love the XL resurrector cartos from Crystal Clear Vapes. Haven't had a dud yet and they hold a lot and last me a solid 7 days if not longer (that's with heavy use.) For batteries, I'm a sucker for pretty, so I have quite a few eGo Q's. (With the resurrector's I don't even miss that they aren't VV.)
I've only looked into DIY juice a little bit. It scared me.

Besides, given a choice, I like to eat out any chance I get, so why would I want to find something else to do in the kitchen?

Building my own wicks? I don't think my brain works that way.
