I have a pair of Ultegra PD-6700 pedals for sale, used but in perfect working order. Comes with box but no cleats.
They are gun metal grey in colour and have cosmetic scrapes from usage. Very happy to send on photos.
RRP when new: £90; this pair for sale at £35 inc postage. Drop me a line at darren [dot] millington [at] gmail [dot] com if you're interested.
