Well DISH has talked me out of an upgrade for now. I had been waiting for the 922, but since there is no TV2 output I decided to find out more about going from 622 to 722k. The DISH guy tells me that it will cost: $100 Upgrade Fee $ 95 Technician Installation Fee So now I think I will just keep my 622! That seems pretty expensive to add two features: -larger hard drive (500 GB to 1 TB) -dual over the air capability Plus they renew a 24 month contract. Are there any other compelling features that I am missing here? Purely from an economic standpoint, I can add an external hard drive and get more memory. Might they have some special offers to waive these fees? I am just anticipating that the $100 upgrade fee is for somebody to enter a few keystrokes in a database. As far as the installation fee, I can't imagine that it gets much simpler than going from a 622 to a 722k. Speaking of memory, has anybody here tried a Western Digital My Book 2 TB external HD? They still tell me over the phone that there is a 1 TB maximum size limit.
