i don't think berninas are still manufactured in switzerland.
i tried tracking down accurate information about that last year.
all i could find was that they were assembled somewhere in "Asia."
that does not mean they are no longer a good machine.
that is always going to depend upon whether the brand owners still hold the assemblers to high standards for machines designed with excellent specifications.
for me, personally, i also think the brand owner should pass on their labor savings to the consumer if they have outsourced manufacture of parts and/or assembly.
i have never heard a bernina owner complain about her/his machine.
they brag about them enthusiastically.
they also still have a reputation for holding up for many years.
so, if you can afford a bernina and are most comfortable with that brand you should be able to buy one with confidence.
