I was lucky enough to find my Willy (free to a good home) and we are in PA. We are near the New Holland Auction barn and they told me Minis run through there sometimes for practically nothing
They are having a min/pony auction in December if your interested. I also found that if you just keep looking somnething may come up I was going to get a mare who was older and sounded wonderful but I had to pass due to some surgery I have coming up and just couldn't take her right now
I am still distressed about that...perhaps you can post on the free "want" ads on this forum http://www.lilbeginnings.com/saleboard/ it is a great place Good luck! If I run across anything I will let you know.
