After seeing CG mentioned on here I've been reading about it online and have decided to give it a whirl. I've ordered the book and a microfibre turban thing, but I'm visiting the Big Smoke today and I'd like to get stocked up with the products I'll need. Otherwise I'll have to wait for the book then order stuff online and wait for it to arrive, which I'm far too impatient to do! 
From looking online I think my hair type is 2b (or possibly 2c). The hair underneath curls much, much more (proper ringlets) than the top (more of a wave than a curl).
So, what do I need?
