Advice on locating used microscopes locally

Does anyone who managed to buy decently priced secondhand microscope have any tips for attempting to locate one locally? I have checked the usual places like FB marketplace & Craigslist but not found anything in my area (greater KC MO area). I know that some people have luck with ebay but I would like to avoid if possible as shipping would be non-ideal IMO.

I already do have a microscope (I got the JTTM kickstarter scope with plan objectives) but I wanted to start looking for an upgrade that would let me build upon it as I fell further into the rabbit hole (that & having a heavier/larger scope in general would be nice to reduce vibrations seen when recording).

Any info/tips would be greatly appreciated! I still have some time before I could upgrade d/t financial constraints with a new job, but I want to start watching the market to be better educated for when I am able to purchase the microscope!
