What would be a fair price for a MicroP25RX, w/WIO terminal, white case, memory card and power supply? It does have an issue where not every plug will work in the audio jack (been that way since day one).
There are unconfirmed reports that Todd is deceased, so the risk with buying any BTT products at this point is there there is now no hardware support. Since much of the software was on GitHub, that could hopefully be picked up and improved upon, but that's about it. I would say going rate would be based on less than what it sold for, +/- the fact that no more are being made.
I'm aware of the post here as well as the posts and claimed identity of the poster on the BTT support forum. I guess what I meant by unconfirmed for someone slightly cynical is an obituary or something more official than a rather anonymous forum post.
