Well... that depends.
Are they more expensive UP FRONT? Yes. Quite a bit so.
But from what I've been reading here, once you get the hang of taking care of them, it will be drastically cheaper.
And besides that, as far as e-cigs being more hassle than cigarettes, well, that depends on how you smoke.
I roll my own. Loose tobacco, rice paper, and skinny filter. Making a cigarette takes me probably about a minute. I can do it in 20 seconds if I'm REALLY pushing, but it won't smoke that well.
Get a filter, put it between my lips, take out a paper, pinch a precise amount of tobacco, sift it across the paper, roll a few times, place the filter and re-arrange tobacco, roll s'more, then tuck (which sometimes takes a few attempts), lick, and stick.
And then after that, light it, take a couple little puffs, then blow forward to put out the flame that ALWAYS seems to happen. Take a couple drags. Get talking for a few second. It goes out. Light it again, oh crap it's on fire, blow forward. Take a couple drags. Get talking. It goes out. Light it again, oh crap it's on fire, blow forward...
You get the picture.
Point is, I go to a lot of trouble to smoke. And trust me, if you were tight enough on cash, or concerned enough about the additives in tailor-made cigs, so would you.
If you don't want to have to deal with dripping all that, get a cartomizer. You can refill 'em in about 2 seconds with the "condom method" (no, it doesn't involve an actual condom), and they're cheap.
No dripping. When one carto runs dry, pull it off and stick on a new one and fill the empty ones when you get around to it.
That's the route I'm going.
