MA'AM MALOU: Why not consider the reference-grade OPPO BDP-103D DARBEE edition Blu-ray player? We have several units for sale at P32,900 (plus P400 in courier delivery). All the three models you've cited are not available on our shore, and on the event someone will sell you they're bound to be 110 volts. The Oppo's difference is that it has the Darbee Visual Presence video processing which lifts the picture to a superior level (even notches better than the standard Oppo 103 which has the Marvell video chip) and delivers superb sound. For the models you've cited, we have tested and owned the Sony 790 and while its picture is equally on par with the Oppo, it has a flimsy build, hit-or-miss reliability/durability and is not as versatile in accepting all kinds of media unlike the Oppo which is a certifiable universal transport. The Panasonic 500's picture is no different than its cheaper counterparts like the 210, 220, 230 and 330 and fares poorly in DVD upscaling, and its touted sonic edge may not even matched the Oppo's. We hope you'll consider our unit, its brand new, 220v, very durable and is not sold elsewhere in the land. Salamat po, ALICE GO #09202-833-970...
