You did indeed get lucky. Amazon sells the Lexar Professional 128 GB for
$275. Yes I know there are cheaper cards, but I have used only the Lexar
or Sandisk. I have read too many horror stories about other brands. I
will go with the odds.

Capacity sounds about right. When I shoot landscape I shoot at most
about ten frames per hour, fifty if I am bracketing, (Since there is a
lot of DR in the D800, 1 EV difference is not very meaningful,
Therefore, I need five shots to get 2 EV difference.) If I want to do
panos, could be significantly more, depending on the scene.

No argument from me, on that. my personal preferences are to use 32 GB
cards, as that is usually enough for a days shooting. I figure that if I
lose a card, I only lose that day.
Remember I have two cards in each of my cameras.
