Another (still older) option on the Cannon side is the D30 and D60.... these pre-date the 10D. I actually sold a 10D for like $120 earlier this year (body only, no battery charger or any other accessories). Pretty much anything pre-dating the Rebel XT / 20D (so: 10D, D30, D60, Rebel) will be too annoying for a pro to use: the time to turn on, even from sleep, is several seconds. So their market is limited, even as a backup. Rebel XT and 20D (and all later Canon DSLR's) turn on in less than a second and are still used as backups by many.
You would have to search and wait patiently to get a body+lens setup for under $200, but it is definitely possible. And, if you don't mind the DSLR vs. P&S tradeoffs* then it will be well worth it.
*DSLR -'s: No video (for older DSLR's). Must look through the viewfinder to compose the photo, not the LCD screen. Significantly more size and weight.
DSLR +'s: Image quality much better. Autofocus much faster. High ISO (low light) performance much better. No shutter lag.
