I sent you a PM as to where I got my case from. I have one at home, a hard metal sided "train" or cosmetic case. When we go out we have a black and silver hard sided hand held case. It's about 6 quid. I love it. It holds quite a bit as well. Here is a pic.

My ecig is a little on the long side once the tip is on the end, if I need to fit both of my bigger cigs in the case, I just take the tips off.
i also have random little zip baggies with extra tips or cartos in them that I slip in.
