If you can find a (now discontinued) kodak DC290, it has 2 critical 
features that have allowed me to make mediocre multi-exposure HDRs: 
First, they save lossless Tiff format images ( I suspect that jpeg and 
even DV compression will give different results for different 
exposures). Second, the camera uses the Digita OS, which is scriptable. 
By writing a simple script to do appropriate exposures in sequence, I 
can make this camera not only capture the exposures, but also export a 
text file suitable for driving the mkhdr utility.  The proces works, 
but I was dogged by standard difficulties of the multi-exposure 
approach, like finding an absolutely static scene for the 3 or 4 
minutes it taes to shoot all the exposures.
