Technics av control stereo recieversa-gx550 in Coombs, British Columbia

I bought this unit brand new for just over $700 and it works just great as the day I got it . I upgrade to a lg disk, dvd ,cd combo The unit has a few marks on the top . I bought another one a few months just a high end unit with front vcr hooks up and sub woofer plug in at the back It is 320 watt unit. May trade for a zotac video card around 3 years old this is a large card.
