I just wanted to say THANK YOU (yes i shouted, some of you live far away) to everyone who replied.

I bought one.

YAY. And the lady i bought it off is friendly and helpful and so even handing over the money was pretty cool. She was all into embracing menstruation - well, i'm not quite embracing it yet, but i'm taking steps to make it less bloody annoying every month!! (no pun intended )

I'll have to tell you all how much i love it when i get it. If i tell non-BB friends they'll think i'm completely mad...
