The "fatty" looks exactly like a Joye eGo.  No clue if it's simply a re-brand of Joye hardware or if it's a clone.  The kit price is high, but not too bad.  You can get a genuine Joye eGo from Liberty Flights for $50, the eGo-T 
tank system starter for $65, or Riva kits for $45 or less (Rivas are eGo clones).  Considering there are places that sell non-eGo 510 starter kits for $100+, $65 for the Fatty doesn't seem too bad.  The main thing that bugs me about the Vapor Toker site is that they don't state anywhere that their devices are 510-compatible.
