Unfortunately, Panasonic doesn't see the US as a good market right now.
Too many cheapskate consumers and not enough smart ones.
I'm disappointed, too, because it is, so far as I can tell, the best brand.
There should be a way to import one, if at a considerable additional cost.
Since today's TVs have universal power supplies,
there should be no concern about voltage and frequency.
One problem might be the built-in tuner,
which will not necessarily be capable of ATSC reception,
but if you don't care about over - the - air, that won't matter.
Warranty coverage will probably not be available.
(But who needs a warranty if the thing isn't likely to fail to start with?)
