No knowledge of e-cigs or pens, first purchase

Hi guys,

First of all sorry if this is a shitty post, im noob. Im looking to pick up a wax pen for dabbing on the go, but am pretty overwhelmed by everything- batteries, coils, globes, mods, wattage, its a lot more complicated than herb vapes.

Whats a solid, entry level pen that will get the job done? Budget is around $100. I usually get crumble or shatter, so whatever works with that.
