In days past I'd recommend a iStick 20-40 and a Nautilus mini or full size. Use the factory coils with clear or unflavored juice and they last a long time.
Today I'd recommend a iStick Pico with a Kanger top tank mini. You can use factory coils or the RBA (wind your own). Less messy because of the top fill, does not leak unless you leave it in a car on a hot afternoon (all bottom coil tanks will leak under these conditions).
Personally, I use the RBA's. I might dryburn the coil and rewick every few months. I just unscrew the top and fill er up once a day. Toss it on the charger when needed. Very low impact and easy.
