Not me, I was a RYO smoker. No way I was gona pay those big bucks for smokes. When they got up over $20/carton I went to making my own.
Paid $35 for a machine and made my own smokes for about $1/pack. When the FED's added $23 for a lb of tobacco, everyone went to pipe tobacco. I am suprised the FED's haven't added the big tax onto Pipe tobacco. It's still about $18/Lb while cig tobacco is around $35-40/Lb.
True, true. But most of us weren't doing RYO and were getting smacked around by the "sin tax" thing. So in the general case, a good, mid-range kit is about a carton worth of cash. Considering we're talking hardware that can last a decent amount of time, it's worth not skimping. At least not too much. A carton of cigs, you were just going to burn. A vape kit can be with you a while.
Kind of like if you'd bought a crappy RYO machine. It's not saving money if you buy something that breaks all the time and has to be fixed or replaced a lot.
But, also, kind of like RYO, with liquids you can cut cost a lot. The premade is nice. It's convenient. And can often be made by expert types who do really great stuff (lot of "boutique" flavors out there that are really, really good). But it's kind of like food. Can you afford to "dine out" or are you on a McDonald's budget?

Or worse, is McDonald's the "splurge"? Me, I can't cook. No talent nor instincts for it. But I gotta drag myself to the grocery store and buy stuff I can make something tolerable out of. Work is glacial slow right now.
And you can do your own mixes with liquids and save a lot. I like some of Johnson Creek's stuff but figured it up and I can come in at a third what they cost. Plus got some recommendations in the DIY liquid section here and cut that even further. Found I can buy bulk nic juice for half or less what I was paying before.
So I suggest people "bite the bullet" and get a good, solid kit. Then focus on cutting liquid expense. That is where the long term cost is.
(And I just noticed you're already doing your own mixes so you know what I mean. I should try that "reading the whole thread before posting" thing. I hear it's all the rage.

Ah well. Ima let the post stand. Somebody else might get something useful out of it. Maybe. Or not. Sometimes, I think I just type for the fun of it or something.)
(Why yes, I am weird. What makes you ask?)
