I will be in London for most of Friday (30/1/09). Please let me know of any secondhand camera stores in the (vaguely) central area. I know about Nicholas in Camden and will be visiting there (even though they were closed last time I went!) and I will be going to Aperture (for lunch as it is a café as well). I have also found Camera City just round the corner from Aperture. I would like to know of any similar shops - not more than a couple of miles from central London as I will be on foot. I don't really want to use the underground unless I absolutely have to. Thanks. Steve.
