One thing should be mentioned. None of these machines are made for the U.S. market anymore. The only "drawback" to all of these models ... no ATSC/QAM tuner(s). Hence the reason they are not made for the U.S. market. ATSC tuners are now required for players in the U.S. Or they will be soon. Not sure if there is an exact date for manufacturers to include ATSC tuners or not.

Do you still see these machines on the store shelves in Canada? They have all but disappeared in the U.S.
