I bought my first ecig somewhere around April '09. It was after a trip to Vegas and they tried to sell me one on the strip for an atrocious amount. I knew enough at the time to go back to the room and research it and glad I didn't get caught up in their spiel. Unfortunately I spent A LOT of money trying different models and juices and quite frankly it ...... me off that I couldn't find something that really WORKED for me. I liked the idea of the whole deal, but it was just too inconvenient in a lot of ways not to mention people constantly asking (especially back then) what I was smoking (funny looks).
Fast forward 2 years and several ecigs, mods, juices, etc. and I think I have found at least a steady baseline to keep myself off of Marlboro's. The day I traded my Prodigy V2 for a really sweet eGo setup changed everything. The eGo is small (650 mah) and with the mega atty (LR), it is dead perfect for me (dripping). The 5v of the Prodigy was a "smoking" sensation that I was looking for (for its high voltage), and although it is a seriously solid piece of equipment, that damn thing looked like I was carrying around a little league baseball bat. The mega LR atomizer gives a somewhat similar throat hit, and I found out a few days ago that tailpiping that LR atty was a very pleasant surprise. I personally think it reduces airflow so you get more of what you want (VG or PG if you prefer) and less air.
My current setup includes:
4 eGo batteries (650 mah)
Multi 510 charger from TW
2 LR mega atty's
24mg 100% VG Backwoods Brew Maple Tobacco mixed with Cinnamon VG from American Eliquid Store (PG seems to hurt my lungs)
Tornado Tank (2 atomizers and 10 tanks on the way from TW)
My fallback setup which is close to a daily vape is the V4L battery with PCC and refilling cartomizers. I found that for me, refilling cartomizers is such a huge, daily PITA. I definitely think that some variation of the tank system is going to take vaping to the next level for a lot of current smokers. I know for me, I feel a lot better not dragging on that nasty smoke every day. I have always HATED my own second hand smoke, the way it sticks to my clothes and my truck, etc. I was up to about 1 and a half packs a day and 17 years of smoking (the number 17 and years seems like a LONG time when you see it on black and white on the screen).
I don't know that I could have quit just cold turkey like the males have in my family in the past. I think cigarettes today carry a lot more chemicals, etc to make it harder to ween yourself off even with patches or gum. I still crave an analogue every now and then and had an analogue the other day from my smoking buddy at work (we are kind of like THE smokers of our company). It tasted like ..., and I felt like a dirtball after smoking it.
Anyways, when other smokers ask about how to get into it I usually point them to these forums for information. The problem in the recent past has been how many variations are out there of the ecig and the liquid. It blows my freaking mind that I could basically try a new juice from a company every day for the next year and maybe not smoke the same one twice. Not to mention that local availability is severely lacking, so your only choice is to place an order and wait impatiently only to find out that that really sucked and light up another analogue. It would be really convenient if there were local stores in every city like TW in Florida where you could go in and try some stuff out before blowing your hard earned money on something that you don't like and have to spend more time to get rid of it or shelve it.
I wasn't planning on writing all of this, but it's a true story that can probably be told by a lot of current vapers out there.
My advice to anyone wanting to move from smoking to ecigs is just to hang in there and keep trying until you find something that works for you.
AFTERTHOUGHT EDIT: My other advice is to start at 24mg/36mg on your juice. I started too low and I don't think it was satisfying enough for me to drop the analogues. You can always cut it down with some VG from walmart or water or whatever if it is too strong. Another epiphany for me was buying a high nic juice and getting a more satisfying feeling from many less vapes.
