I seem to remember it is £5 but what that equates to I don't know.
However it does seem to suggest that the system is flexible enough to
charge different amounts on entry at different stations and this amount
might need increasing a bit to allow for travel to ungated stations way
outside the zonal area.

Don't forget, stations within the zonal area don't need to be gated, just
provided with an Oyster validator - agree however the major problem will be
people travelling 'long' to beyond the Oyster zone - and risking a normal
revenue check by an inspector or a manned barrier somewhere, but this is
also the case at the moment with people taking a punt on the likelihood of a
ticket check at the further outposts, having entered through a gated station
with a normal magnetic ticket to the first stop...
