I got a 25 dollar Rick & Morty glass piece.
Then added a 35mm e-rig combo deal for $125 ( Quarts banger, insert and carb cap, heating coil and controller )
I leave it at 450F and leave the bong dry. Much more heat that that and water is nicer.
I don't enjoy vape pens very much. The cheap 510 carts are harsher than the Dime ones I buy. The Dimes bother me, even on the lowest temp..
Wax is a better value and it taste better, smoother. I prefer it over anything else.
A wax pen isn't bad, I used one as my only driver for a few months.
Had an Arizer extreme Q, The are a good value for the money I think. I think a Mighty is a really good vape as well, just pricey. Probably heats better than the Arizer.
Planet of the vapes has a $99 One vape that might be what you are looking for. If you like dry herb vaping.
