Sigma DP2M AND a DP1M: $2000
Your favorite stitching software: $100
Completely freaking awesome landscape kit and I just saved you 4k.....and back troubles later in life since this is so light.
Heh - I knew someone would make an attempt at a better deal when I posted that ;-)
The DP2M and DP1M are definitely interesting little cameras. After I complete some of my Nikon kit I really might think about snagging one... would be perfect for carrying in a pocket while skiing ;-)
Sorry, I couldn't resist.

And that said, I can't understand why anyone who shoots landscapes wouldn't choose one over ANY full frame dslr. The quality of the images I've seen is astounding. As far as a pocket camera goes, I'm not sure it would be a good choice, handheld it is a difficult camera and from what I've read the live view is awful. But I am getting one soon, there isn't anything that can touch it for landscape work........... especially for the price.
