The plinth is just cosmetics, smoktech I have gotten, as far as I recall, from ivapour-elixir, there is also smokshop, which I reckon is the official uk distributor of all things smok, liberty flights I think, probably others, but still, who knows, another supplier may have ace boges, and ace boges are the biz...what you linked to is an iGo-L, vapingthings are great, sometimes more expensive, sometimes cheaper, but they have great customer service, I once ordered a steel geni tank there, and a glass tank tube...and the guy texted me saying that the glass tube I ordered was for a different steel tank, and so we sorted something out, and I tell you, many vendors would not have pointed that out, diamond geezer runs that joint.
Edit: Yeah, I know what you mean about the crack pipe look, sometimes I like things that look like they have no forsaken reason why they should be put together, why should everything be flush and smooth, right.
