If there’s a research college or university in your area, check what they do with their old lab equipment. They generally like to replace a machine long before it wears out, just so they can stay current.
The state university system here has it’s own store where they sell the old equipment, usually by auction. But, the auctions aren’t advertised all that well, so the equipment often goes for a song. Everything from glass beakers to mass spectrometers to DNA synthesizers, and yes, sometimes freeze-dryers! They may not be as consumer-friendly as a Harvest Right, but they would do the job.
That’s a great idea.
