Ideally you want to stick with something you know you'll like.
As juice said, it may serve you well to find out what you've tried and look on the web.
If you can find a shop you KNOW you can TRUST, that can be an endless source of knowledge.
Keep in mind, almost every shop will cost more than online, but good knowledge is priceless, especially as you start your journey.
If you don't know what gear you tried think of it this way:
If you're trying to quit smoking only:
A pod system like the juul or a good all in one kit like the innokin t20 would be a nice starting point to get you off smokes
If you're looking to quit smoking and start down the path of hobby vapor.
I would look at something like the aspire Nautilus for a tank (tried and true tank for smokers) and a nice single 18650 mod like the pico 75 with that you'll want 2 18650s and a charger.
If you're looking to get into clouds bro clouds, a nice 200w starter kit would be nice. I don't know much about what's on the market there but I'm sure someone more knowledgeable here can advise you.
It's best to figure out what you want your device to do for you before you buy it
