This is true but not absolutely necessary (high dollars $$$). A less power-
ful (read 'less expensive') scope will do just fine (especially for the
beginner).
 
>Special media preperation is involved
Not necessary for just the beginner or hobbiest.  Remove head, remove
collar and look inside, you'll find the mites if you've got 'em.  It
takes a little practice but the technique works fine once you figure
it out.  There is no need for elaborate prep work if you're not actually
counting or recording the number of mites per bee or doing some other kind
of "highly scientific" work.
 
Now, who has some "cheap" scopes for sale??
