Good maps of Essex, suitable for bikes?

[Magnum]

I've been exploring the local area, and i'm going to venture a bit further into essex tomorrow and i think i need a map incase i get lost. What good maps are there of essex that would be compact enough to carry on a bike?

I carry an A-Z map of East Anglia about with me, either in my tankbag or under my seat.

+1 The A-Z East Anglia map is best,easy to read and clear available Smiths, stick it in a poly food bag under the seat.
