I love BE! I'm a recent convert, having just got my starter kit, Fair foundation (which doesn't come in a kit - unfortunately), Clear Radiance, Bisque and Well-Rested at Sephora in the San Francisco airport before I flew back to the UK after the holidays. In retrospect, I should've bought more as the exchange rate was good. I've only been using it for a week and a half, but love the way it feels and the fact that I look like I've got great skin, instead of looking like I'm wearing make-up.
I have ridiculously pale skin (living in Scotland doesn't exactly help) and if they were to come out with an even lighter shade of foundation, I'd be happy.

For now the Fair is ok, and it looks like the Fairly Light will be my colour for summer (woohoo for fake-tan that doesn't turn me yellow or orange).
I'm contemplating getting some of the eyeshadows next, and was thinking about Black Pearl and perhaps the Meet the Plums kit. Does anyone have experience with either of those? I've been addicted to Chanel's Quatre Ombres for years now but could be persuaded to branch out.
The one other problem I have with BE is that they don't stock it at ANY major shops in the UK (Debenhams, House of Fraser, Selfridges, Harrods, Harvey Nichols, etc.). They've got it in Italy and France, but neither of them will ship outside of their country - not even within Europe; which means I either have to pay nearly double for it on smaller UK websites or order it from the US and have a friend forward it to me.

Le sigh.
