For an e-cig cig look-a-like I would look into the Volt models from what I have heard they come highly recommended. For a step above that I do not think you can go wrong with a KGO/Riva or E-power as they offer better battery life and higher voltage. I would also get some cartomizers in both LR (low resistance) and SR (Standard resistance) so you can try them both. Also
e-liquids in different ratios of pg/vg and nic level. This will help you to begin to figure out your preferences. At the beginning of
vaping it will take some trial and error to find out what it is you like and dislike and unfortunately there aren't many shops where you can try before you
buy. So the initial cost is more than smoking, but once you find your ideal set-up then you will start to see the cost savings as the replacement parts and juices are relatively inexpensive when compared to cigarettes. Good luck.
