Hi there, I am a month in myself. Started with an ego c twist, and a protank 2. I now have a vamo v5 itaste MVP v2, 20 different types of clearomizers and protank types and a ton of Boba's Bounty! I recently got an igo-l rebuildable dripper, and got it to work awesomely the first try! it was magic.
I then ordered a russian 91% a couple more drippers like the igo-l and a TON of supplies to build (torch, silica, cotton, kanthol, mesh and all the small tools to help) I am in love with building! So much easier than I thought once i did the first one. Dripping is so much nicer than anything else, except for the fact there is no tank.... but that is where the Russian 91% comes in (or anything like it). It is night and day from where I started, and I couldn't go back.
You sound like your already head deep into the rebuilding idea, so I would say GO FOR IT! Get what you can afford, and have at it. I think the igo-l dripper is a great start for anyone. It is so easy and simple to test out coil making, and at the same time, you get a really great (CHEAP) dripper to test ejuice out with. The kayfun style RBA's are an amazing thing to have. I bought a clone russian, as I said before, and I wouldn't think twice about recommending it to anyone. Watch the videos on rebuilding, do some test runs with different gauge kanthal and get the "feel" for it. There is definitely a small learning curve with coil building. I am not getting into the crazy stuff yet (like that total nut rip trippers... JK RT your awesome), I followed Pbusardo, GrmmGreen and vapingwithtwisted420. Watched them over and over before my items came in, then sat down to try it myself. Now I feel pretty confident in what I am doing... I can even wrap coils to specific ohm's from memory, it is awesome.
I love vaping, and so happy I quit smoking. I am also proud to be part of this community with all you awesome people. I wish you all the best, and as I learn, I will pay it forward to the best of my ability.
