current ideas on P680 structure

Greetings, Photosynthesis Netters:

I just finished doing a brief lit review for a presentation regarding 'the
structure and function of chlorophyll at many scales', and I spent a good
deal of time reading some chem + molecular work on PSII. Curiously, I did
not see a clear consensus regarding the structure of the P680 reaction
center of PSII. 

The most recent work I found was a Nat Acad Sci paper by Durrant et al
that suggested that the structure was a chl multimer. I found another ref
to a European J Biochem paper by Santini et al that provided x-ray
crystallography data for a dimer structure, but it was 'OUT AT THE
BINDERY' and I couldn't read it. 

SO -> I wanted to pose the general question to the PSYN-NET readers on
this subject:  what is the current state of thought on the structure of
PSII and its reaction center in higher plants? Thanks.
