Having just recovered from a nasty parasite attack with my fish, I am
interested in buying a suitable microscope to assist in early diagnosis. It
is a long trek to my nearest koi shop with a bagged up fish so a sample can
be taken when there may be nothing to check.

Can anyone in the UK recommend a type & source for a suitable microscope at
a
reasonable price? Mail order or within 50 miles or so of
Sheffield/Chesterfield area would be ideal.
