Hi Krispy, and welcome.
Since you apparently "kinda" smoke, there is nothing particularly wrong with wanting to
vape to enjoy the "social experience" of smoking with friends.
I use 510's, eGos, and recently got into the 901. I like all of them, but I can tell you, from a "cig type" experience the 901 is very nice. It has a nice draw, kinda like a cig, and I actually kinda like it better than the draw on my 510's for that "cigarette experience".
For what you ask, let me tell you what I have been doing lately. I get my 510 and 901 supplies from
www.ValueVapor.com - Deep Discount Electronic Cigarettes . He has really good prices, not only on starter kits but the individual pieces. I get the SLB 510 and 901 batteries and atomizers there. Buy the pieces individually and you can save a good amount over a starter kit. Batteries are 9.99 and attys are 4.99. A USB battery charger is 4 bucks. He sells juice as well, but not zero nic. It's a great way to try an ecig type and spend minimal dollars.
For liquid I get most of my stuff from
Best Electronic Cigarettes - Freedom Smokes Inc. . Good prices and good service. You can get zero nic there in tons of different flavors, and right now you can get 20% off with the coupon code Liquid20. You can also get 40% of kits and hardware with the coupon code FREEDOM. I have used both recently and gotten some really great deals.
I hope this helps you.
Steve
