The issue is complicated
Really, the ones you *really* want are the ones who are completely unavailable...Already in relationships, and unwilling to cheat. Next best (as a broad generalised category) is probably widows.
Apart from that, anyone who has had a relationship is, to some degree, 'damaged goods', and like any relationship, the trick is finding a partner with whom the good is fantastic and the bad is tolerable.
