Hi,
My favorite way of creating 3d images is with a twinned pair of canon s90s as described here http://stereo.jpn.org/eng/index.html.
I use http://stereo.jpn.org/eng/stphmkr/index.html to create the .mpo files.
There is a yahoo group that provides additional information http://tech.groups.yahoo.com/group/StereoDataMaker/
I also purchased a Japanese version of the Panasonic 3d1, which is much more convenient, but the lenses are too close together for general photography, but good for candid photos taken around a table.
