These are the lot I use mate:

Find them to be very good, if you order before 3pm it goes out the same day which guarantees next day delivery.
Started with one of the beginner kits which comprised a couple of batteries, a couple of clearomizers, a carry case and a bottle of the liquid to get you started. Still use that kit when out and about but I also picked up this huge chrome beast of a thing to use at home.
Can definitely recommend the Whisky Cream flavour, tastes like Baileys
