I have recovered bikes for myself and for others over the years.
Growing up in the mean streets of Brooklyn NY, we'd just pay the guy who had our bike to get it back.
We sort of hoped the person with it, didn't know it was stolen.
Here in Oregon I had my garage broken into and a bunch of nice stuff taken. I got the insurance $$, but then as the bikes surfaces I bought them each back. One of from a guy who bought an abandoned storage unit, it was clear he knew he was buying stolen, then abandoned stuff, but how can I prove that versus just getting my custom track bike back for $130?
Another bike in that whole deal surfaced at an OBRA members friends former drug dealer. I gave the friend $500 and the next day he gave me my bike.
Being an above board, regulated industry employed guy, I told the insurance about it and they didn't quite have a square hole for my round peg, so they let me keep the bikes.
If it was me, I'd buy the bike from the guy who has it, then worry about looking up hill once you have the bike back.
