Paul,

Yes, the Rebel XT is on the short list of candidates.  The Canon image 
processing software has an excellent rating among the SLR brands- perhaps 
the best.  Both the Rebel XT and the Zeiss D40 are about the same size and 
price.  The Rebel APS sensor has a bit more noise than the Zeiss D40 CCD, 
according to http://www.dpreview.com/  , and the Zeiss got great ratings on 
short "time delays" (time from "on" to "able to take picture").  However, 
the Zeiss D40 doesn't have focus motors built into the camera body- its in 
the lenses (and the kit lens isn't an autofocus lens).

So, everything is a compromise.
