For the price, I'd recommend the Sub-box Mini kit from Kanger, and using Samsung 25R batteries (get at least two, and a good charger from Nitecore), and don't forget to buy extra coils when you buy the kit.... Flavor, vapor, and durability are all subjective, and will depend on the juice you use, PG/VG ratio, and how well you take care of your equipment. But I think you'd be very happy with the Sub-tank mini and Sub-box mini combo kit... they run ~ $60 US (not sure about EU pricing).
