Dang it, I can't remember the website/link that I've been trying to remember. I think it was a dealer somewhere in the Midwest that specializes in used hybrids of all kinds. Maybe someone here knows where the info for that was posted; I thought it was here, but it could have been on another forum elsewhere.
In the meantime, maybe try Autotrader, or cars.com, or findmyinsight.com
Good luck.
PS: I found the link I was trying to think of:
