Hi Hayden,
Welcome to ECF!
For under $100 there are a TON of kits that you could go with. The one I would recommend would be this one
Kanger Mini Protank 2 Starter Kit -VV. It is a complete kit (minus juice) and gives you everything you need to get started, plus 2 batteries so that you have a spare while one is charging. It is an awesome deal for the money and the value you get out of it.
I would also recommend picking up a bottle of VapeDojo's Blueberry Vanilla Tobacco ... it is very tasty! Oh, and don't forget some spare coils. 2.2 ohm coils are about the most flexible range available. I would suggest 1 box (5 coils about $7-8) to see if they work for you.
HTH
P.S. If you need more recommendations, try looking at the iTaste VV (but you will also need to buy tanks) and the MVP 2 also ... both would be great starter setups as well. Whatever you decide to go with, I HIGHLY recommend buying 2 batteries so that you have a backup should something go wrong (as it often does).
