ECLIPSE 800

Hi I need advice on a microscope camera for the Nikon eclipse 800 I know they can get expensive, however I require one that must be inexpensive as the it is 16 years old or so and dont want to invest 5000-40000. If you had a good experience with a cheap camera please let me know I want one for 500 or less and I will use micromanager to run the imaging part.

thanks

Darryl
