If you're talking about a tank you don't have to build yourself, but instead could replace it with a prebuilt coil head, then try to Protank 1 (later version like the Protank 2 and 3 left some people disappointed). It's as easy as rinsing, drying, and installing a new prebuilt coil head. The Protank 1 might not suit your taste aesthetically like the 2 and 3, but in use, it's probably the best of the three.
Now, I just received the brand new Kanger Aerotank. It looks and in my opinion performs better than the Protank 1, and I like my Protank 1. So far, I'd highly recommend it for someone that wants a tank, without the hassle of playing with wires and wicks. This is coming from a sub-ohm vaper that uses an RDA for casual vaping. When I'm on-the-go, I like to use my tank, used to be my Protank 1, but now the Aerotank.
It's easy to clean and all that, but I wouldn't go dropping it. It uses a Pyrex tank to hold the e-liquid. I've dropped a tank before and stayed intact, but I'm still careful with my devices. There's a battery in it afterall.
