I don't have time to do a proper appraisal right now, but as I glance at your list the ones that hit me immediately as interesting and potentially good are MedicalClinic in org and ReporterStory in com, and a bit less but I do like myUSAhub in com too.
I think the myriad of uses possible for MedicalClinic are obvious, and the org is a good extension for it as well. Clearly it is at least a high $$$ and probably somewhere in $$$$ name (I say off top of head without searching for comparator sales).
I like ReporterStory a lot but wonder what ideas you have in mind for the end user. It would be a great book related site for a journalist autobiography, but doubt that would generate a very high price. Also, some sort of reference site for investigative stories maybe? It is one of those names that strikes me as very good, but I am still struggling with marketable ideas.
What is the status of edu.eu? Do they carry restrictions re only European educational uses, or are they wide open? Would affect market. I like, especially the jobs one.
