HI all, I would like hear from those who purchased own their VIP722/722K DVRs. It is worth it (for about $200)? My current leased VIP722 is showing signs of pending hard drive failure (e.g. video/audio stuttering in recorded shows when recording multiple shows at once, unable to rewind OTA shows when all three tuners are recording ). I spoke to Dish support about replacing my existing VIP722 with an identical model or even upgrade to 722K or 922 but I was told the available replacements they I can get are 622s and some other lower end models. They said 722/722k/922 are not available for me. They did recommend me to upgrade to Hopper though. If I choose not to upgrade to Hopper and plan to use VIP722 for many years to come, and if hard drive failure is something I may have to deal with every couple years, is it worth to purchase my own VIP722 or VIP722K? Given the information I have read, I would be able to replace the internal hard drive myself without dealing with Dish's customer support or waiting for replacement units to ship to me. Any opinions on this subject is welcome. Thank you.
