I bought a cheapo juicer for the fast so I intend on buying oranges to juice. Last year I purchased fresh juiced orange juice at my local health food store.
I think the broth part is personal and based on what you are wanting to do or able to do. You can always buy store broth and spruce it up with veggies and such. That would be a good search to do on this forum ... to see what others have done.
