There are lot of different directions you can go. Many new vapers like to smoke MTL style, with less vapor but higher nicotine and a smaller battery and etc. They tend to consume less ejuice an battery life if you are seeking something small and easy to start. The aspire zelos mod is small and portable and comes as a kit with the Nautilus 2 tank, (which was my quitting tank) and it worked. You will have more control over your vape (airflow, wattage, coil type, they make different resistances) and can try different things. The kind of eliquid you use will also make a difference, and you will likely require experimenting there. MTL vaping is usually between 12--24 m.g. (although some folks go higher). You can get sample "juices" from vendors in small amounts to try and see what you like.
With that said, there are newcomers who enjoy DL (direct to lung) sub0hm vaping right from the beginning. It's hard to know what will "suit" you until you try some things. You could get a two battery box mod, and then you can try different atomizers (toppers) to see what your preference is, and if it's MTL the worst thing that will happen using a larger mod with more battery life and just enjoy your lengthy battery life. Tons of good, fairly inexpensive setups on the market, and you could try both type of vaping. Due to the volume of vapor, DL style type vaping typically uses lower nicotine in the 3--9 mg/ml range, as you absorb more vapor per puff.
Finally, no matter what you choose, you will probably need to do some experimenting with both juice and equipment to find out what works for you. I had to do that, and did make some purchases along the way that weren't suited to my vaping, but sometimes it's just the only way to find out. It's unrealistic to think someone can find the "perfect" setup for you, as vaping is so individual. I will say, once you do vaping pays for itself rather quickly and if you find a setup or two that you like, you will rapidly begin saving money. I rolled my own tobacco so smoking was less expensive for me than many but if I count health costs I have saved tons of money (and even with rapidly amassing a large stash of vape gear, LOL). I also DIY my own juices, and that is a cost savings as well (plus, I enjoy it).
Welcome to ECF, and don't let the dizzying array of options turn you off, approach it like an exciting adventure!
