Also to Paul,
Although I may not agree on the equipment choice for someone just starting, I have to agree with John D on just about everything else. It is a horrible fate, to be fated to tobacco cigarettes.
Get a good kit. Get vaping. Find the equipment and liquids that you like, it's an adventure and one that will change your life. And, never, never, never look back. There will always be someone you can look to in the vaping community to give you advice and encouragement. You can be smoke free, and I'm looking forward to the day I get to say "happy 1 year smoke free!"
Paul - Please do not "get a good kit". Most "good kits" will be constant voltage. Variable voltage is indisputably superior to constant voltage.
The Joyetch eGo-C Twist has a dial on the bottom that lets you adjust the voltage between 3.2 and 4.8 volts. That allows you to control the amount of watts produced by/within the coil. It is as easy to use as a dimmer switch. It can be taught is three seconds. For more heat to the coil, turn the knob clockwise. For less heat to the coil, turn it counter-clockwise. I do not understand why so many people give beginners so little credit concerning basic intelligence.
The Vivi Nova tank/atomizer is insanely easy to use and performs very, very well. Unscrew the top, fill it with juice to the "Full" mark, and vape.

The soothing background guitar music tells you it's simple.
I have been vaping for almost a year, and have bought LOTS of stuff. Joytech eGo-T (constant voltage) tank system, Joyetch eGo-C (Constant voltage) tank system, Smoktech Woo 5-volt battery, e_power (constant voltage) battery), Smoktech VMax variable voltage APV (awesome, $100), Joyetech 18650 (constant voltage) APV, and others.
Right now, I am vaping on a Joyetch eGo-C Twist (variable voltage) APV with a Vivi Nova 3.5 ml tank/atomizer. Anyone with a functioning brain can operate this equipment, and I cannot recommend it highly enough as an excellent starting point to use while you explore other options. As for me, I just plain like it, and my VMax sits largely ignored and unused, awesome as it is.

The Vivi Nova video mentions that it comes with three "heads" - the actual atomizer that is fed with wicks. The heads come in three different "resistances" - amounts of "ohms".
The higher the ohms, the more volts are required to achieve a given amount of heat, measured in watts. With a variable voltage device, you can adjust the voltage to achieve any desired heat using any of the three heads. You CANNOT do that with a constant voltage device.
The Joyetech eGo-C Twist is indeed a game changer, allowing anyone to have variable voltage for a much lower cost of entry than ever before.
