I am looking for inexpensive  microscopes that will magnify up to about
300X.  I have been given a catalogue (1997) for

    EFSTONSCIENCE Inc.
    Science & Technology Agora
    3350 Dufferin Street
    Toronto, Ontario M6A 3A4
    Canada

I was going to call them next week for a new catalogue so I don't
know if they are still in business. If you have any luck with
distributors in Canada will you let me know.
