I need to add a VERY low cost receiver to my Dish Network account for about 3 months and don't want to buy a new one for such a short time. I don't need a dish, just the basic (non DVR) receiver and any needed card and remote. I was looking on ebay and one person says the card doesn't matter since Dish needs to send a new one, is this fact or fiction ? I have been out of the sat biz for several years now so am not sure what to look for on ebay or even here if there are any used units to be had.
