I haven't read all 5+ pages of this thread so if this was said already, sorry for repeating. Here is a basic check list that I give people who are dedicated to finding something to help them make that huge lifestyle switch from smoking to vaping.
Take into consider; your budget, what you are looking for in vaping, that your taste buds will change as time goes on that you haven't smoked a cigarette and the fact that the first few juices and setups you try...you might not love!
Checklist:
-2+ Ego style batteries (do yourself a favor, don't gimp out on batteries. Go 650MAH+ and get at least 2)
-Cartomizers, Atomizers, Tanks, Carto-tanks, Clearomizers...whatever you are curious about..do research and give them a try! Each different juice delivery system produces a different vape. Some might produce more vapor but gimp on the flavor a tad and some might do the opposite.
-SAMPLE PACKS OF JUICE! holy crap I can't stress that enough...when you are first getting into vaping get SAMPLE PACKS! A lot of vendors sell sample packs of juice (5+ different juices in usually 5ml bottles) they can be bought for cheap usually and you can sample a ton of different flavors. I recommend getting at least 2 sample packs to start with, if money isn't an option get 3+ from different vendors. I've had a plain menthol flavor from one vendor that tastes 100% different from another, since it isn't mass-produced and it is handmade, the making and flavors are different per each vendor.
Starter vendor list:
madvapes.com(fast shipping, out of north carolina, great customer service and decent prices!)
fasttech.com(out of chine, ok shipping, most of the time this is a great vendor to buy from for cheap batteries and parts if you aren't in a hurry)
ecblends.com(good juices, I see you have already tried them...so try some more flavors from them!)
vapor4life.com(ok prices, decently fast shipping)
namberjuice.com(great juices, ok pricing and fast shipping)
Hopefully my little wall of text helped you a bit. Of course if you want to jump right into things like APV's and whatnot, the checklist I listed above will have to be modified by yourself.
