Similar to what happened to me. I just order Dish (Everything Pack, HD Ultimate, etc). I have 4 HDTVs (2 DRV, 2 normal) to feed, and 3 SDTVs. I ended up, after about 2 hours on the phone with the CSR:
1 722 (Dual tuner HD DVR) (counts as 2 TVs as far as the limit of 4 leases go)
1 612 (Dual tuner HD DVR)
2 211 (Single tuner HD) - had to buy one, lease the other
Kept the SDTVs on cable for now - dealing with 4 TVs was hard enough, can't imagine how long it would have taken them to figure out how to handle 7.
On another note, they would not, under any circumstances, sell me something other than a 211. I asked about a price on a 612 or another 722, I mean, if I'm spending $249 to buy a 211, I'd be happy to pay an extra $250 per so and get a DVR. No doing. Even his supervisor said that they could not sell me a 612 or 722 - which I find just weird.
