Mvp2 is great, had mine about 5 months and it's still doing it's thang.So, I just ordered an itaste MVP 2.0.
Is this something I can learn to build onto?
Went this way because it comes with a built in battery and I'd rather hop into trying to build coils/atomizers and seeing if I can do that, before adding the battery expense as well.
Using a smok Catapillar rda single coil build @ 1.7ohms 12 wraps on 18ga wire nail. I always see everyone mention "taping" one of the air holes on rda's with dual sides, i leave them both wide open and it rips at 5v. It also has adjustable air flow holes so you can set it wherever it works best for you. I picked mine up for $20 bucks from a local vape shop simply because it was the only rda they had in stock at the time.
Once you get your rda you can play around with different builds till you find what works for you.
