I was kidding a bit about the Provari in post #9. If you want to fill the APV voids left by the Provari look at the Sigelei Zmax Telescopic V3 or V5. Both are very well-built, full featured APVs. V3 will give you these features the Provari can't: battery versatility with 18350, 18490, 18500, 18650 and 2x18350 without optional extension tubes, VV/VW operation, 510/eGo threading with one-piece stainless steel threading, the smallest size of all VV/VW tube mods at all battery sizes, removable top cap and a superior OLED display screen. V5 will add two additional features to what is found on V3: cell phone charger and a puff counter.
The other void left by the Provari (and Sigelei) APVs is sub-ohm vaping if you want it. For that you want either a quality mech mod and suitable batteries or a DNA type APV. You might have a hard time finding a DNA rig at the price you are looking at.
