if i'm in the market for a mega dvd changer, about how much should i be expecting to spend (i can ebay)? the player itself doesn't have to be amazing... i just need component output and progressive scan really. but i would like to house my entire dvd collection so i'd say i'm looking for something that is capable of holding 300-1000 disks. so far i've only seen a 400 disc changing sony on bestbuy's website. i suppose it's okay... but what else is out there?
