Being overwhelmed is common for people who just start vaping. Being ripped off by shops that take advantage of your ignorance is even more common. You've come to the right place though, because you can learn everything you need to know right here and it's all free.
For a newbie who is just starting out I highly recommend sticking with an easy to use, basic starter kit with clearomizers (tanks). Eventually you'll probably want to get into more complex stuff, but it's much easier to figure out what is best for your needs after you've learned all of the basics.
There are 3 basic starter kits that I would recommend. They all work basically the same way, they all provide good vaping at low cost and are easy to maintain, and they are all cheap enough that you won't feel like you've thrown away money if you want to upgrade to something larger or more complex later.

The most simple and easy ecig to start with in my opinion is the Halo Triton. It's about as easy as they get to use. Charge the battery, fill the tank, and that's it. Once in a while you'll have to clean or replace a coil, but that's simply a matter of unscrewing the coil and washing it really well, let it dry, and then putting it back in, or simply screwing a new one in to replace it. Tritons are not the cheapest starter kits, but they are very well built, very reliable, and work great. It's what I use the most.

My second recommendation would be an eGo Twist with a clearomizer. It's almost identical to the Halo in size, appearance, and the way it works. However, the eGo will have more options available as far as toppers (Clearomizers, cartomizers, cartotanks, etc...) They are still really easy to use, typically priced a little better than a Triton, and you can find parts for them virtually anywhere. They also have the advantage of being able to adjust the voltage to increase vapor production and/or improve the taste depending on your preference. (Tritons also have variable voltage batteries, but you have to buy them separately) The downside is all of those options can be overwhelming and it takes a bit of research to figure out not only what type of parts you want to use, but who makes the best ones.

The third option would be the Innokin VV. This is very similar to the eGo in the way it works. It uses all the same toppers as the eGo does. It's variable voltage like the eGo is, it just has more options in regards to the variable voltage settings. It's still really easy to use and includes passthrough USB charging abilities so you can continue to use it while you're charging it.

Those really are the 3 easiest setups to start with that will be low cost, provide a lot of vapor, and are solid and reliable products. They're great starting points to let you learn what you like, don't like, and would like to change. Many people are happy using one of these exclusively and never look for anything larger or more complex.
