I can't find many eGo kits with standard size cartos in stock, but madvapes does have a kit with the whopper eGo sized dual coils - MadVapes 510 Ego Mega Dual Coil Cartomizer Kit
Once you have a kit like this, you can add a box of regular sized cartos (Boge LR or XL dual coils) of your choice and a cone (optional) and you'll have a lot to work with. A couple flavors of juice to start and you will get off to a good start.
There's lots of info on ECF on how to fill your cartos and top them off. A syringe isn't necessary, just drip slowly down the sides until mushy at the top.
So this is what I would I get with it?
Dual Coil Clear Mega XL Cartomizer
and then all I would need is juice and possibly a syringe?
