Welcome Hayden, and congrats on your success with ditching the cigarettes. I also started with a Blu kit, and after a few days realized I needed to upgrade to something with longer battery life. Lots of folks here recommended a Kanger Evod starter kit, so that's what I got. I haven't smoked a cigarette since then, over 2 months!
It comes with everything you need, 2 batteries, 2 toppers, and a charger. All you need to add is the juice. Here is a link to the kit from a reliable vendor. If you use the code ECF at checkout, you get 10% off, making it only about $30:
