I stopped following the vaping scene because it became a real money pit and my current setups and snake oil serve me well. However the nemesis clone from Fasttech (iirc it's around £25) can't be sniffed at if you want to venture into mechanical mods.
I have a nemisis clone, best mod i have had yet. and they only £15 on fasttech

Also the Stingray clone is catching my eye, not sure if it any better than the nemi though

Its really up to you Rilot. go for either a genuine mod, it will be over priced but the sell on value and demand should also stay high.
Or get some clones that look and perform virtually the same as the real thing, but the sell on value will be low.
Also agree witht he money pit statement.
I have a nemi clone, vamo, kfl and a kayfun 3.1 clone and i do not really need to buy anything else as this setup works perfect for me.
I may just get another nemi or the stingray with a dripper and that will be all the equipment i will need.
I cannot see the point of spending hundreds of pounds for virtually no performance gain over what i have already.
Vaping seems to breed a culture of the more expensive something is, the more people want it.
If its better or not is not important, its the exclusivity that matters.
