A toroidal will be more expensive than a conventional transformer
(but lighter weight and cooler to the touch).
You may want to go conventional.


30VA is a bit big for a wall wart.
If you get your own steel box
and make a "brick" that lies on the floor or tabletop,
you should be good to go.
As Steve said, fuse it.
