Once you learn a bit about different devices you'll be able to find one that closer meets your needs. The first one you get may not be the best one for you, so be prepared to purchase another.
I like Aspire PockeX or Ego AIO or Kanger Evod kits for beginners.
They're simpler plug and play devices. ENJOY the journey! Cheers.
