Great. Ego-T is a good choice. Before you buy you may want to go the meetup. There are usually local vendors. We really are quite nice and non-judgmental.
I have been vaping 2 1/2 years. I average 4 cigarettes a day with espresso. E-cigs are an alternative. Nobody has come up with a successful cigar alternative, though there are some cigar flavors available. BTW, drip, cartomizer or tank. Nobody uses cartridges.
I smoked 3 packs a day for over 30 years. Some of my fellow vapers are the same.
