Since you're just starting, I'd experiment with a couple lower priced mods before diving headfirst into...I really shouldn't talk lol, but you need to figure out exactly what type of vaping style suits you best, as multiple people stated before. Honestly, the chipset is the most important part of the mod, and naturally, it should be aesthetically pleasing to you. There are so many mods out there, some that aren't expensive at all, that deliver incredible performance.
May I suggest a Smok Alien 220 kit? Comes with a tank, all you do is add batteries and your favorite juice and vape away. A mod like the Cartel Revenant might be perfect for you. It has one of the slickest boards in the business, and it's intelligent and will recommend you a wattage when you install a new atomizer...each and every time. You can also do temperature control and customized wattage curves...it's a looker, too. Top it off with an atomizer of your choice (again, that comes down to your vaping preference...I'd recommend a tank with a drop in coil for a new vaper...like maybe a Smok TFV8 or Uwell Crown...it really depends on what you prefer) and you have a great setup that will last you for quite some time.
