Did I misread your post? DISH offered you a pretty good deal on an upgrade and you don't see it as such?I'm torn, I have a 622 today and would like something with more recording capacity and capabilities, so hopper or genie both are attractive.
DIRECTV is willing to pony up around $800 dollars (Q2 2012 SAC was $789, Q1 2012 SAC was $816) to find your wallet because they're pretty sure they'll wring most of it out of you during the first 24 months. They don't give deals because they are nice.
When you're doing your cost comparisons, don't forget that DIRECTV charges about the same for their OTA tuner.
