The drip tip can be purchased here for 3 dollars.
I think for under 32 with out batteries and a charger is great. You can get 4 batteries and a charger for under 9 dollars, so for under 41 shipped you can rock that amazing looking mod with a charger and 4 batteries. I remember a year ago when epipes not this cool where over 200 bucks with batteries and a charger. The mod is not mine. It is Archaviator. I just think it looks really cool.
Disclaimer. The Protank v2 I linked to is the clone so it will look simmilar but not exactly the same.
