I have paid no real attention to the HDTV discussions here in the past but I am now toying with the idea of a plasma screen TV. Aside from the expense of a plasma TV, what are the Dish Network expenses? I assume I have to get an HDTV receiver and would obviously want one with DVR capabilities. Are there any Dish Netowrk "deals" for existing customer, or do I have to fork out hundreds of more dollars for a new receiver. How does this compare to Cable TV,do they give their HDTV capable boxes away for free ?
