Ok, ignoring taxes and credits, let's look at my current bill and options. I will assume that I would lose my no-locals grandfathered status if I moved to the Hopper/Joey system. If I could keep that, it would be a big incentive and knock $5 off the right 2 columns, and almost certainly tip me over the edge.
I have two single mode ViP722 HD DVRs connected to two HDTVs, and a DTVPal driving a 36" SDTV. The other SDTV (27"), which I would never connect to Dish, is in the exercise room and er, uh, let's just say it doesn't get used much.

I would consider a Joey at the 36" SDTV but I would be inclined to get two Hoppers, but might go with a Hopper and a Joey (because of that $199 2nd Hopper fee), for the two HDTVs and leave the 36" SDTV with just the DTVPal. Before I would make any change, Dish would have to get the two Hoppers seamless, and the OTA module working, simultaneous multiple EHDs, and I'd pick over the wounds from the arrows in the backs of those pioneers.

What price convenience?
For giving up one tuner and redundancy, or paying an up front $199, I can save a dollar a month and add locals (no interest, watch very little big 4 networks, and have excellent OTA antenna system). For an extra $6 more than I pay today, I can add another, infrequently used, TV. The up front costs will never be recouped, they're a write off for convenience. Or have I miscalculated?
Of course, I'm overlooking the $99 up front, unless I'm a cat A customer. Gee, I know I'm one of their most valuable customers.

Never late, on autopay for years, AT250 w/BB & protection plan, few calls or visits (IMO), Dish customer since 12/01, have actually turned down freebies, brought a few customers to Dish (of which they only know of 1 or 2), high credit score (just refi'd, I
know) but rarely buy PPV, but sub'd for about a year to HBO et al. I guess since I didn't get an email offering the ViP922 for free, I've missed the mark. Maybe needed to go AEP & buy PPV regularly?
BTW, I consider such a system would last a minimum of at least 2 years, and more likely at least 4, before the next upgrade. This factors in any recouping of up front costs or buying a Joey and activating/deactivating it as needed.
I welcome and look forward to any comments.
