So my third 622 is showing signs of failing. Not enough though to make this a critical decision at this time but with prices increases coming..... I only run my 622 in single mode. Any upgrade done via DISH for other than a Hopper is only going to get me a reconditioned unit(ie; 722k) and yet another two year contract after years of being without one. Would a single Hopper/Sling receiver give me everything I have now plus of course the Sling feature or am I missing something? I guess my fees would go up $4?? To avoid the contract I most likely would buy from Dish Depot as I have read here. Thanks.
