Ok youngunner you have two possibilities here.
1- Go with the 510 Indy Kit. It's $45 and comes with one full 510 e-cig and a PCC, which is a personnal charging case. What this does is allows you to charge the PCC which will then charge your 510 e-cig about 6 times. Then all you do is recharge the PCC. This is great for people on the go.
2- Go with the 510 Recharger Kit and then buy a charger from the accessories section. This will cost you $50. But for the extra five dollars you get 2 510 e-cigs instead of one. Its just kind of up to you on what your lifestyle is. If you are always on the go then the Indy kit with the PCC would probably be your better bet. If your not worried about being away from a USB for any long period of time you are probably better off with the Recharger Kit. But those are your best two options as far as price goes.
Hope that helped you out.
