Hello! Had to pop in. I've been vaping for years now and I've spent enough time here on e-cigarette-forum to have earned a masters and PHD in vapology, too bad that isn't a thing yet.
I'm with Baditude that you should definitely at least begin looking at the REO mod.
I have owned everything out there. I've owned and used genesis style mechanicals. I own and used a Provari for the majority of my years spent vaping. I have several mechanicals. Have a pipe style rig. Ego batteries. All I can tell you is that spending time here on ECF equates to you wanting, and acquiring, a lot of vape devices. You see things, and you wind up feeling you should get them for yourself.
I started researching vaping right around the time it became popular, around 7-8 years ago now. The ONLY things on the market for vaping were cigarette styled batteries and pipe styled batteries. I started on an all white 510 kit myself. I settled on the Provari as my main PV for the last 2 years or so. Loved the Provari more than everything else combined. Tried Genesis devices on it.. Though they were good, they took too long to rewick and coil for me. Tried clearos. They're great, but I didn't like buying more when I ran out. (I couldn't, I've been unemployed or self employed on a tiny income for the majority of the time I've been vaping...) Finally, I tried rebuildable dripping atomizers. Got my hands on a couple and a big spool of kanthal, some cotton yarn from Walmart.
I haven't looked back.
Dripping is where this vaping thing comes together for me. I can control how much juice I'm using per vape session, per hit. I enjoy rebuilding my own dripping atomizers and I love knowing I'll never run out of what I need to vape. My last clearo will never break. If something goes wrong, I can rebuild a RDA in 5 minutes.
I bought a Reo years ago, but it was a Reo Mini, it used 14500 batteries. I used it at home a bit, sure, but I could only take it out for short 1-2 hour trips to the store. I only had a few batteries for it and I could only vape it for a few hours. I sold that Mini, and I immediately bought a Reo Grand with the money I had received. Now... I literally haven't used my Provari in almost 2 months. All I use is nice, solid mechanicals and my Reo, with rebuildable dripping atomizers, my "A7s" have never failed me. In all honesty, I would literally be tempted to trade 90% of my collection for 1 more Reo Grand.
Do not get me wrong, Variable Voltage is great. You can up the voltage for various needs, down it for different needs. But vaping strait from a battery, with a LOW resistance, cannot be beat. Once you understand mechanical vaping and low resistance rebuilding, you've graduated. There is no need to go back. There is no need to use any regulated mod. You can "regulate" each hit with the time you spend pushing the button down. The Reo Grand, holds 6ml of juice on-board. Which means I can "drip" without having to take out the bottle every time the coil dries up. I just squonk the bottle and my Reo is wet and ready. It's a sturdy device and you can use a multitude of bottom fed RDAs atop it.
Trust me, if you have values in line with the value's and expectations I've listed above... & If you trust the experience of someone who's been vaping since the beginning, then you will at least consider the Reo line of mods.
