My own thoughts, as I struggled with my own problems with
vaping...
Rebuildables seem intimidating at first, *really* intimidating, but they're not; it's just a new thing to learn, and that's what brains are for. I got so utterly sick and tired of replacement coils, the cost, the hassle, the constant waiting to see if vapemail would arrive before my last coil got trashed... so I started learning the rebuilding, as a way of taking control. Once I figured out that it wasn't as scary as all that, I got a Kayfun... and that was really a turning-point; I could finally TASTE what I was
vaping, and I could get excellent TH without having to stand on my head and hold my mouth right. I figured out that rebuilding is actually the EASIEST way to get a great vape, and the cost is so low, it's hard to measure.
It's true that tanks can present problems of their own, though I've had zero issues with my Tobeco Kayfun Lite Plus's, and even the EHPro KFL+ is pretty solid, but if you want something a little simpler, the Magma RDA is an excellent choice; easy to build, deep well so you're not needing to drip *constantly*, and the vape is just outstanding. Clones of those are not expensive; I got a Tobeco clone of the Magma from eciggity, for $18.99.
I had a hard time at first, finding an ejuice I could use as a replacement for cigarettes, but fortunately after just a couple weeks of searching, I found "Virginia" at MyFreedomSmokes, and it was PERFECT. Now I don't even like it, it tastes TOO MUCH! like cigarettes, but when I started out, that was just what I needed, something similar enough that I didn't feel a lack. Whatever kind of cigarettes you preferred, check MyFreedomSmokes; they have a comparison chart for all the major American brands, to help you find an ejuice that will suit your preference.
For mods, my personal preference is for mods that use removable batteries; to me it's just easier that way, recharging batteries daily rather than having the mod out of commission while it's charging, but there are quite a few mods nowadays that have the "pass-thru" feature, so you can still vape while they're charging (though the charging takes longer, used that way). I've seen a lot of good things said about the iStick 30 and iStick 50 and the various MVPs, but personally I'd recommend a Sigelei-ANYTHING; excellent quality, and they won't break the bank. My Sigelei Zmax v3 is nearly a year old, and it's by far the most dependable device I own.
If you want to keep trying and keep vaping, quit trying to do the same thing over and over; you're just going to get the same results. Look into rebuilding, get a Kayfun or a Magma; you'll get excellent flavor and very little hassle. The mod you put it on is less important, as long as you keep battery issues in mind -- no super-low resistance on batteries that can't handle it. I personally thought the Nautilus sucked rocks, and sold mine within a week of buying it -- and right after that, I got a Kayfun, and discovered that vaping doesn't have to be hard -- but it's always going to take a little more effort than smoking. If you just can't handle any effort at all, then by all means, go back to smoking; it's easy, and really easy to damage your health that way too, but it's your decision; only you can decide if your health is worth some effort to maintain.
