Do you want parts or the whole thing? Enlarger being big and bulky but not worth that much, many retailers in my area hates to carry them. An owner at one used dealer I often deal with says, he hates to carry them because they take up space, sits there forever, and not bring him in much money. He sold me two for basically taking them away. Shipping would be prohibitive for buyer too. Even on APUG, most sellers specify local pickup only.
As much pain as it is, your best bet maybe a local classified, Craig's list, etc.
