Shinhom have some:

Their prices are pretty good, but MOQ is usually 600 - 2000.

If you're only after a few then the quickest way is probably to rip up
an ATX PSU - they have a push pull transformer that does mains voltage
down to 12V, 5V, 3V3 and -12V they also have a flyback that does AC to
5V at 2-3A for the standby power.  There are plenty of schematics for
them on the web, there's very little variation from brand to brand -
someone good did the design about 20 years ago and it's been endlessly
copied with minor tweaks.
