>>2277Yes building your own coils saves money. I bought a bunch of wire and cotton and rayon and I have more than I will ever use now. Like seriously I probably have a 5 or 10 year supply just getting different wires to try. They aren't expensive, I probably paid $14 for the giant box of rayon, more than I will use in my lifetime, $5 for a giant bag of cotton balls (this is the only thing I will need more of, and probably not for a year or two), and $8 for each spool of wire. This stuff is absolutely cheap compared to what you will end up spending on any sort of box mod.
Just get a small bundle of organic cotton balls and a thing of 28g kanthal.
Wrapping coils is easy and if you get a regulated box mod you don't actually have to worry all that much about ohms other than getting it over the minimum limit for your box mod.
