I started on the same type that you're on. Stop by your local B&M and check out the iTaste variable voltage battery with a dual-coil pro-tank. Also get an e-liquid that's 50/50 between vegetable glycerine (good vapor -- 'clouds') and propylene glycol (throat hit).
That's the best place to start. The mod scene is totally overwhelming. Here's a basic breakdown:
Low ohm - hotter liquid / pull
VG - bigger 'smoke'
PG - throat hit
Higher wattage - fuller flavor / mouth feel
Higher voltage - thicker pull
I'm in the same subreddit -- it's amazing what people come up with.
