My favorite mechanical mod is the Novice clone I have, it uses the 14500-14650 batteries. Keep buying and using what you like but I would highly recommended getting and setting aside at least one mechanical mod. Just my two cents, lol. Oh and you don't need the Vape Fuse for APV's as they have built in protection.
I really like the looks of the Novice and am surprised how inexpensive! It is hard to shop online when so few give dimensions of the products. I see one vendor about 40 miles away and looked at their website (expensive!) but may be worth stopping in to look next time I'm out that direction. I buy most things online as we are in a rural area.
The plan now, get a few with the electronics like the itaste 134 or SID and the Novice or similar to put away for "insurance". I will need to continue I do some more reading to learn (accused of being obsessive/compulsive more than a few times!) . I am trying to get my husband interested as he has the background in electronics. Use to be when I mentioned stocking up "just in case" or wanted to wrap our coils and DIY juice, he'd say "I just want to stay off cigarettes, I don't want another hobby." Now he says buy more nic, also worried about price as well as availability and must consider the juice I make vapeable!
