Norman,
Awesome! this is much easier to deal with. There is no metadata with it,
but it looks like it might be the 1 arc sec, 30m/pixel, data in a 16bit
tiff. How do I interpret the pixel values? as meters from the ellipsoid?
Thanks,
-Steve

How much data are you trying to download? You can still find some of
the DEMs as a file download without having to deal with the seamless
site.

Or at that size, perhaps bittorrent.
Or, another potential place -- an Amazon Web Service Public Data Set:
http://aws.amazon.com/publicdatasets/
"Public Data Sets on AWS provides a centralized repository of
public data sets that can be seamlessly integrated into AWS
cloud-based applications. AWS is hosting the public data sets
at no charge for the community"
I find their pre-loaded PostGIS open-street-map and 2008 TIGER/LINE
data extremely convenient:
