I'm another lover of it.
I have a Green & Blacks 70% in my cupboard to nibble on. That bar actually came with a free taster bar of the one with cherries. Haven't eaten it yet, though.
I haven't done much exploring of what's available over here, but in the States, I used to love trying new varieties. When I worked in NYC, everyone knew that I'd always have a couple high-quality bars in my desk (along with a big jar of M&Ms, to stave off the less serious people), and a few coworkers would come to me begging for a square. There were many times I felt like a crack dealer.
