I have two ViP722 DVRs. First one is free. Second one costs $17.
Here's an example:

AT250..................................... . 69.99...................... 69.99......................................69.99
Second duo receiver....................17.00
---$7@.second device fee...........................................21.00.......................................21.00
BlockBuster................................10.00......................10.00.......................................10.00

---DVR+Whole House fee..........................................10.00........................................10.00
Protection Plan..............................7.00.......................7.00..........................................7.00
.............................................$109.99.............$117.99..........................................$117.99
Plus taxes and state/local fees, possibly including regulatory cost recovery fees, if any. Depends upon where you receive service. Where I live in VA, it's a bit over $3/mo.
Second Hopper means a higher up front fee, probably around $100. And $8 per month more. Personally, I think you'd find the 2H/2J system the best bang for the buck. All TVs get an independent HD signal plus other features.
Of course, if you pick a lower package you'd save money, as you would if you dropped BB@Home and the protection plan.
