On the main site, I asked a question and got several good answers that gave me good avenues to research. Based on another meta question I did not 'accept' the first good answer that came in. This was good advice since several other good answers came in. I upvoted all the answers I thought were good but still haven't accepted any because now I have the dilemma of several equally good answers.
I noticed on a different question that someone made a 'combined' answer of several other contributors answers. They attirbuted what they got from others. Is that an appropriate way to deal with this, ie I answer my own question with the combined answer of others? That wouldn't seem fair to me.
Following the advice below (from @Fortiter), I'm summarizing what I consider the best answer and including it in the question (how's that for recursion).
