It would also be nice to get one that did not have the 110v. option.
Presumably this could be produced cheaper and could be smaller

Probably wouldn't make much difference, the 110v socket will just be fed
from a centre tap in the transformer secondary so you're only saving on
the cost of the second socket. The transformer would be the same size
and probably governs the overall size of the unit.

Why would a transformer be needed for a 240v. toothbrush charger or a 240v.
razor ?
Surely the only "transforming" necessary is to cope with the 110v.
situation.
