I would recommend this, then:

Aspire Atlantis (Simple) Mod:

I also recommend buying a Replacement Coil (5 Pack):
I also recommend buying the extension pyrex tube (5mL of juice instead of 3mL of juice)
Cheapest E-Liquid, BEST fucking quality flavor:
http://www.drcrimmy.com/store/pc/home.asp (125mL for $32)
Look at the reviews on YouTube, everyone loves his products.

I also don't think that mod requires you to know battery safety or Ohm's Law, so I recommend that.
