This is my advise and no way saying all that has been said is not a good suggestion. If I were to have it to do all over again here is what I recommend. ecigexpress.com. 1. Get a Joy eGO mega starter kit. Has 2 900mah batteries and charger. Other items I do not use anymore. Except the attys. 2. Get a extra box of 5 attys510's. Derin(sp) drip tip. I would suggest the mega cartomizers but now the tanks are avail I will be using those. Juices are very good, taste is subject to your taste. Alot of suppliers are avail to try. Get small bottles in the nic level you want to experiment with. Til they have the tank you will need to source these out. Got mine from TW along with the cone attys. You have your batteries, attys, drip tip for fast vape and good TH, I use this for trying new juices and when I have the time to drip. The cartridges are ok but I went thru the foam phase, and now have access to the tank. Tried the mega cartomizers, and still do but will be replacing with the tank. I have tried the auto batteries in a more look like a cig or analog, but battery life is less than I like. You could get parts and build a starter kit but cost is less if purchased in a kit to start out with. Bought seperatly is more costly.
I now order an extra battery when I buy juice and up to 6 so I will never be with out. Throw in a couple extra attys 510's just to have. I hope this helps, I wish I had found this forum before I spent all the money I did learning what works for me. I hope the ego tank is as good as I have read about and the cone attys are too. Now that I have plenty of batteries in a power I like as well as size it will be my way to vape til something better comes along, as in a better juice delivery system. Good luck and welcome. Oh one thing else, I shopped around before I settled on ecigexpress, and they are as a complete sourse as alot of others but found to be the best priced, not on everything but for shipping and overall cost per item equally priced.
