Mo - we got it off e-Bay. It is Cherub brand. It hasn't arrived yet so can't say if it works well or not, but it cost $17 including postage.
Kim - dodgy chinese food! I bet you won't be getting food from there again. Thanks for the note re the bottle warmer. I will have to test it out before we need it. Can't imagine having L screaming for 45 mins for his bottle to warm!
