For that money, I'd get a Provari.
Well I've got a provari -- but I want a Provari shaped like this!
I just love the carto tanks but don't like the length and don't like when my carto breaks off when I drop it (I've never actually had one break off in my pocket). I also still feel a little silly with the provari + tank in public.
I would be happy for this in wood too, but the one's I've seen don't have the tank fully recessed and still look a bit bulky. This looks well designed with thought put into minimizing the size.
If they could maybe make it longer (although it may be long enough already) to get the kick in there, and then maybe go one step further and put a little screw in there that allowed you to adjust the kick without taking it out -- then we would be talking! I would pay more than $200 for that!
Keep in mind the $200 includes batts, chargers, and a tank, too.
Basically I want this to be popular so that other modders/manufacturers build to this form.
