I started with a 510T with regular 180 maH batteries... my husband used one, and I used the other. We fought for the charger sometimes, and bought a second kit in no time. The megas are definitely worth the money. As for an extra atomizer, 2.5 months later we still use the originals. I went through my first 30mL of juice in just over a month, he used his in just over 2 weeks. I was a half-pack a day smoker, and he was well over a pack a day. Two packs would last the two of us about a day and a half. For kit, I think you have picked great, and for price, you are really taking a hard hit. You should be able to get a kit that comes with two mega batteries for about 35 bucks, juice should be about 15 dollars for 30mL, and if you are the only one who will be vaping, you shouldn't need anything else at first.
