You need a 510 thread and then its up to you how many add ons you get. Start at the inhale to go for about a tenner and then decide if you want variable voltage, digital readouts, pre-heat, twin cart etc etc. Just as a hint: a battery is a battery....

That's fair enough! 👊🤣

What are you trying to vape? E liquid? Carts? Extracts?
There's different recommendations depending on the answer

👍

So I started with a 510 pen as I already had it and it was easy to get carts here.

Now I've gotten myself a coil king and am buying extracts standalone. It's got pros and cons. Doing Dabs is generally better as you have more control as to what you're consuming, but it does miss out on the convenience factor

All in all, there's a time n place for either.
510 carts are good for on the go and convenience, but dab pens are probably preferably if you're home and willing to put in the extra effort

Ps. If, like me, you're really adamant on having water filtration, it's way easier to get attachments for a non-510 solution. I got a Hubble bubbler for my coil king and it works a treat (as long as you ignore how phallic it is)

Hope this helps!
