So, I recently got an istick 50w and a kanger subtank plus (which is significantly different from the full size subtank)... , but I am happily surprised. .  My girlfriend, who only smokes zero nicotine is currently smoking a Vision Spinner, with an aspire bdc, but she wants to blow clouds like me. 
  
I am hoping to find an ultra cheap setup for her, that will blow some clouds.  She is a very light vaper, so battery life is no issue.  Honestly, I don't think build quality or flavor are big issues for her either, she just wants big clouds like me. 
  
I'm really thinking I need to wait for the Innokin iSub Sub Ohm tank that GeorgeF posted about in the new product watch.  A sub ohm tank at sub $20 sounds about right for me. 
  
What I really need is the other half (power supply).  Something small and cheap that will power a 0.5 ohm coil.  I'm thinking something like a dirt cheap Fasttech knockoff. 
  
All advice is certainly welcome. 
  
Thanks RadNate
