LimeSDR-USB: Any way to get a hold on one

I’m looking for a used LimeSDR for educational purposes.

I’m writing a thesis focused around FISSURE framework and I’d like to have LimeSDR as a testing device.

Would anyone be willing to part with their LimeSDR-USB?

Thank you in advance for a PM!

You can find them on eBay at a somewhat crazy markup - $1000 vs $300. They also appear to be “unofficial” productions (fair, given the design is open source).
