Congrats on your "first post ever", Jay!
The toroids come from almost as many differing sources as there are
members to the list! Some are purchased (I don't know from where) the
rest are made in a variety of ways, probably the easiest being to get
flexable duct tubing from a home supply center and bend it into a
doughnut and tie the ends neatly together and or tape with aluminum tape.
You could use an appropriately sized conductive sphere in place of the
toroid but it will shape the coils electrostatic field differently and
change it's spark pattern. Although many have used copper toilet floats
as top terminals on Tesla coils, it is actualy a poor choice because its
ridged surface will induce arcing at lower voltages than if it had a
smoothly curved surface.
