I don't know man... I used to do organic tobacco, whole leaf, 50 cigs a day. Rolled my own with papers, not tubes. Cost was around $80 a month. And it was the best stuff you can get. Vaping is cheaper, way cheaper. I can also go hiking, running for a damn long time. I feel great vaping.
Cost wise... I just bought 30 years worth of nicotine base yesterday for $80, plus 2 liters of PG/VG and another flavor. (So that's Feb's $80) Then I bought 2 more Subtank Mini's and another TFV4 and some cotton, and 15 glass replacements, that was $80 (January's money). Oops, and then the Smok R200 - I'm over budget... I'm not saving any money at all! What's wrong! Haha.
Actually, I'm way ahead of the game. I would have purchased a new tobacco shredding device, probably 5000 more papers or some new filters. Maybe I'd splurge and pick up some exotic leaf. And then the lighters, all the time spent cleaning up ashes. All the time spent outside or doing nothing while smoking. Even if I am spending more money on vaping, I'm doing it by choice. I could easily survive with my Sig30Mini and Subtank mini. It works. There is no way vaping couldn't be cheaper than actually buying cigs locally, which is around $5.60 a pack for generics. (Around $13 a day or $400 a month.)
I also don't have the indirect costs of smoking, such as a monthly fee for a dating service. Usually have to find a new woman after I chuck lung cookies across the bed at night. Don't have that problem anymore either.
As far as coil building goes, it took me about 3 months to be able to figure out what coil I like the best, and to be able to make it reliably. What's my favorite? 4x 32 gauge twisted 2.5-3mm diameter, .5-7 ohm. The more messed up it looks, (hairball) the better it vapes. (You can even twist the wires by hand.) Easy build, goes in the subtank mini (or subtank plus) RBA. 1 week, then rewick. 2-4 weeks, recoil. It's cheap, it works great (even at 36 watts!)
All in all, I spend less time messing around with coils and wicks than I did shredding tobacco in a pasta machine. Less mess too.
Good luck, and don't give up.
