I'm waiting for an RSST, 400 SS Mesh, some 32 and 34 kanthal wire, black chrome VAMO mod w/18650 battery, and a trustfire charger. Finally made that next step up from an ego-c and protank setup 
15 more ego starter kits
4 tanks
30 cartos
2 tips
3 ego cones
And 8 bottles of e juice
2 Pro Tanks
20 10mL bottles for my DIY adventures.
6 aluminum tips for 6 T2 or CE5 tanks.
Recently received 20 15mL Flavors and 1 236mL 65%/35% @ 24mg Nic from Mt Baker Vapor - Electronic Cigarettes, USA made E Juice, and Accessories (recommended) for less than $80 including shipping.
Starting to DIY estimated cost savings for a year of Vaping should be around $3200 here in Arizona.
50 pack of 1.8ohm coils for the T2/CE5 tanks.
2 eGo-c twist 900mah batteries. (ROCKS!)
I also learned that the burnable side of a CD is made from polycarbonate plastic like the T2/CE5 Clearomizers are, so you can test your juice with a drop on that left overnight.
If your disk wipes (after a day) clean the juice won't eat your tank and kill you or whatever it does to human lungs/blood/brain cells/reproductive "units" etc.
Tested and proved with Amaretto flavor juice that just ate the CD like it was lunch. mtbakervapor.com sent me a list that flat says it would. It did.
This is why I am on to the Pro Tanks as I want GLASS though I have to say the T2 on the twist with 1.8ohm coils makes for excellent, very low maintenance PVs.
I am hoping the Pro will do the same but really I am perfectly willing to forego using stuff that eats plastic (what does it do to my lungs then?) if needed but I really do like Amaretto.
