$200 buys a lot of stuff... I'd recommend focusing on having two to four quality batteries, and at least four quality tanks (and two boxes of coils). With that in your arsenal of hardware, you can focus on juices and isolate things you like right now. Your tastes will change after a few months of vaping because you'll get your ability to taste "back". AND, you'll have the opportunity to really evaluate your hardware to see if you need something different, or more of the same (later).
