Before you buy a Nautilus, look at a Subtank mini or something with a rebuildable deck (rba). I used a Nautilus 5ml tank for 4 months and found myself wanting more. Also, coils get a bit to be a pain when you have to buy them. I love the option of rebuilding and just getting back to living instead of worrying that I may need to buy or order more and when I will have to get them. Both tanks cost about the same and both are solid choices. I just wish someone would have told me what I'm telling you before I bought the Nautilus. Good luck.
