I have 2 622's. One is leased and the other I purchased about 7 years ago. The leased one is doing fine. The one I purchased is starting to act up (total lockup, front panel reboot brings it back, then happens again and again). I'm wondering what my options will be when I contact Dish. Since it's not a leased unit will they automatically give me another 622 or can I request a 722K or Hopper and if so what will I be charged for either of those? I'd like to be prepared before I contact them.
