Links to Related Sites
These are sites with content closely related to that of these pages. The commercial sites and their products are not endorsed by me, they are here simply to provide the reader with information and choice. Having said that, one supplier has been deliberately excluded because of our extremely bad experience of them (You know who you are). That aside, I would welcome suggestions for other sites which might be added to this list (My sole condition is that commercial site owners agree to provide a link to this site in return).
