Maybe it is just me because I am still 30% on analogs; but analogs definitely taste burnt to me -- perhaps because I use my lighter to literally light them on fire.
In all seriousness, looking at the math, I use 2 cartos in place of one pack of analogs. I just use ordinary cartos from V4L (808D) or SAFP (510). I find they can be refilled once or maybe twice before they start to taste burnt. And you know what I do if they taste burnt? I throw them away because they are supposed to be disposable. Easy.
I smoke a premium brand of analogs and they cost (depending on where I buy them) $7 to $9 a pack. Figuring 2 uses per cartomizer (and it comes prefilled so I only pay for juice for the second filling), my cost is roughly the equivalent of $1.50/pack.
Yes, there are "startup costs." I have four 808D XL batteries, two 510 Mega batteries and associated chargers. Lets call it $200 just for fun because the batteries wear out and need to be replaced.
I used to smoke a pack of analogs a day. $8/day x 365 days = $2920
Though I plan to cut back more, I am still using a pack of analogs every three days, so over a year that is $913. For the e-cigarette remainder I am spending $200 in hardware plus $361 in cartos and juice. So even if I stay smoking 1/3rd of the time; my total annual cost has dropped from $2920 to $1474.
If I were to quit the analogs completely, my annual cost would only be $747.50. But, hey, let's go crazy and just round it up to $1,000. Even at that, it would still only be a third of the cost -- and that is just using the cartomizers as disposable after one refill and really exaggerating the costs.
So I don't really see cost as a big detractor. I seem to have more money in my pocket rather than less.
The burnt taste is definitely yucky and like you I'm sensitive to it. But the solution is to just get regular cartomizers, don't use them to the point of dryness, and throw them out after a single refill. When I first started I over-taxed cartos and ruined them in a hurry. Now that I am using all manual batteries, I sort of have the hang of it and am not burning them anymore. I was going at it with too much intensity. That is, I was drawing too long which cause the wick to temporarily go dry and get singed. Pacing vaping more like drawing on a cigarette definitely cuts back on the singed wick problem.
Different strokes for different folks of course; but even though I have no particular horrible health issues or anything, I feel better for having used the e-cigarettes to cut back on the analogs. Down the road I'd like to cut them out completely but I still prefer the analogs directly after meals, etc.
Either way, I'd encourage you to try the e-cigarettes again. This much I'll say -- the technology is improving and like you I threw out the first batch from a couple of years ago. But the modern stuff is better.
