I don't care for the Feadog...but opinions are subjective. The Feadog has that traditional sound, which can be a bit scratchy/harsh to my ears.

I'll agree that everything on your list above is pretty easy to play for the beginner. I'm a huge fan of the Dixon DX-Trad model, and it's only $28 on today's Amazon prices.
