McMaster Carr has multi-tap stepdown transformers. While intended
for converting 240-480 to 120-240, they would work fine converting 120 to
60. Some derating may be necessary. 1.5KVA is about $150.

You could look for distribution transformers in a scrapyard. These
are basically the same thing as above but mounted in a steel enclosure.
Just make sure you don't get an autotransformer (only one winding) if you
want an isolated supply.
