Selling my HD2-MBX-5G for $8k under list price... am I nuts? I no longer have a use case for it

Spoke with a guy a bit ago that wants it. I pulled it out of the box, plugged it in to my Starlink Residential for WAN and gave him login rights to it via IC2. It’s still got a few month of PrimeCare.
I no longer have a WISP, so my use case is gone. I’ll replace it with a BR2 MAX PRO, or a regular BR2, I haven’t decided yet.
