Congrats on taking the plunge. Watch a ton of videos and read the rebuildable subforum here - learn all you can about battery safety, resistance checking, and coil building techniques. What you'll find with the genny's is that there is a fair bit of debate around coil and (particularly) wick types. Some are 'traditionalists' and preach that only scorched SS mesh can be used as the wick, while others swear by SS wire with an ecowool sleeve to avoid hot spots and shorts. Others, still, will talk about microcoils and cotton wicks, and then there is this whole subohm build scene (the most potentially dangerous style of vaping). Confused? Time for research, then. It'll all make sense if you take the time, do the reading/watching.
I will say don't get caught up in the fashion of extreme builds, cloud chasing, and so forth. Understand your goals (and they are your goals) and build for that.
That all said, I love genny's for vaping. They just take patience and a fair amount of fiddling to tune right. Once you're there, it's a happy place.
