We went with a decent brand that should last a while, it was our christmas present to each other, almost 400 CAD. But like I said we've saved a fair bit in fuels already. Also, the enail lets us portion out our dabs if we're running low, a lot better than a regular rig and nail does. Since it's always hot, microdosing with tiny dabs is easy. For regular users like us it makes sense!
