Recommendations for selling Leica microscopes?

Hi all,
I’m new to this forum, so looking for help/guidance! I’ve taken over some legacy Leica units (DM4000B, DM2500, DM4000M, DMIRBE, DVC500s) that I’d be happy to let go if it helps upgrade our M205C workhorse. I’m wondering if you have any recommendations for forums (like this?), marketplaces, or other channels - preferably in Australia, but one can always ship. (I sent an SEM to France.)

We bought some microscope parts from eBay, you can try putting them there and see what happens.
