Can you recommend a really good non-slip exercise mat?

I am making do at the moment with DS's Cars playmat! We have laminate floor so it needs to be properly non-slip. Does anyone know where I can look for one?

Thank you muchly. :o

I've got one from YogaMatters ordered through Amazon - here it is

sticks very well to my laminate. But when I am sweaty I find I need to put a towel on it to stop my hands slipping doing plank/press-ups.
