Mike, I got the Joyetech EVIC AIO
Joyetech eVic AIO | PVs & Mods | VaporBeast
It is similar to the Evic Mini VTwo, but has an internal reservoir to hold juice. Uses the Cubis coils. Replaceable battery.
However (what I didn't realize) it comes with an adapter to allow for EXTERNAL tanks as well. Not tried in that mode yet, but nice to know that's an option.
I liked the variability of VW/TC. One of the reasons why I shied away from the eGo versions. I *KNOW* I didn't pay as much as VB has them for (I bought two, and I'm thinking they were under $30, definitely under $40 for each.)
And yes, the AIO world *IS* confusing. The concept was the "internal" tank - streamlined, "easier" to use. I also appreciated that they use the same coils as my Cubis tanks. There are RBA heads as well as "prug 'n' pray" heads. Didn't want something for which I needed yet another different coil.....
Krisma has at least one of these, and gave some positive feedback. Now that I'm getting the hang, I REALLY like this thing. My only concern is that the tank appears to be polycarbonate. Would prefer glass, but now that I realize there's an external tank adapter, if the internal tanks gives way, I can still use the device.
