Uwell crown tank, 4ml capacity, coils that last a very long time and produce excellent flavor. Personally I use the .5 dual ss coils but the .25 ss dual coils work well also. There is a 1.2 ohm coil which is kanthal as well but I can't comment on that one, I've never used it.
The uwell crown 3 gets good
reviews and holds 5mls. It seems like a nice tank. It uses a plug and play coil which is easy to replace. With the bigger capacity and the coils you don't have to screw in, it will be my next purchase and is another choice for you if you want a bigger capacity tank.
