I got a bit of shineyitis myself last month and over spent. I'll wait and see how this month goes.
If you're planning on building down that low you'll probably enjoy the mah of 2 batteries. I don't know the size of that mod but I do enjoy having my 2 battery "desk" mods.I keep going back and forth on the cuboid. I want a temp control mod that'll go down to .05 but don't know if I want a dual battery unit. I tend to like smaller mods.
