Building new coils is super easy. I can get it done damn near under five minutes now if I'm not cleaning the entire device for a flavor switch. Granted, being an audio engineer I have a slight background in dealing with and fixing small electronics, but even coming from this point of view I can still say it takes
way less "finesse" than hand rolling a cigarette was for me,
honestly.
Stock up on silica wick from fasttech. They're a quarter cheaper when a quantity of 5 or more is ordered. You can get 15 feet of it for $5.45 shipped.

Kanthal Wire 32 Gauge RW0097 - 100 FT 0.25oz Series A-1 Resistance AWG
A good set of tweezers with different points will go a long way. A rounded blunt one to grab grommets if your dealing with things like the Nova or Protank head assembly, a pointed fine tip one to gently separate your wound coils should they be touching or causing hot spots. Yes, again it's at fasttech.

Lastly, I would suggest owning a plain old multi-meter. You could pay 20 bucks for a resistance checker you screw devices into like you see on many YouTube videos, but really, just get a decent cheap multi-meter from Radioshack, or fasttech. You can check the voltages on your batteries, and the resistance of devices, or even audible continuity checks. Yes your PV may have a resistance checker on it, but why risk connecting something to such device without testing it before? A good multi-meter will cost you $9-$20 and is available from so many places on the internet the only advice I can give is "Google it."
Done!
There are a ton of videos on youtube to walk you through rebuilding. I'm pretty new to vaping, but took to the "rebuilding thing" within the first week or so after learning there was life after a Blu starter kit. I was used to soldering my own audio cables every other day, and immediately just recognized how much money this would save me along with the ridiculous amounts of cash vaping already saved me.
