All new Bailey machines are purchased through the Bailey company. They assemble these mid-arm machines in their shops in N.Y. state. It is a family owned business.
There is a Bailey group on Yahoo run by a QB member, Desertdebbe who also is a sales rep for Bailey (in AZ) and occasionally someone will list a used machine at that board. You might contact her to find out if there is one available at present. They are, I believe, the cheapest home quilter you can buy. Chuck Bailey sells their classroom models so you might want to look into those. Buying from an owner is OK if they are honest about how the machine was used and cared for. Personally, I believe in this case, new is better.
If I can help you further, please feel free to ask.
