Is there a starter kit now, or it's just the tank?
There are lots of people using the tank, and it's usually a love it or hate it situation, it has fantastic flavor but it's a very tight draw. There are also tons and tons of threads about it already, you might want to do a search. It comes in 22 and 24 mm, 2 and 4 ml, and the larger tank offers a "short" 2 ml configuration which I prefer, because it tends to flood less and gives better flavor IMHO. To tight a draw is one main complaint and flooding and gurgling after filling is another complaint. But it's probably one of the more unthirsty tanks you are going to come across and it has great flavor.
Good luck,
Anna
