I currently have 3-301 and one 501DVR under the Digital Home Plan. I believe my monthly bill includes 4x$5 =$20 leased tuner fee and no fee for my 501DVR.I have been considering upgrading/replacing some of my tuners due to the issues with the 501dvr's. If i purchase a new reciever, are there any addtional fees i would have to pay to add it to my account? If i lease a 625 DVR from Dish, does the fact that it has dual tuners change the lease fee of $5 to $10 since it is dual tuners? I know if i upgrade my DVR, i will have to fork over the DVR monthly fee.
