I would say that ISO400 on Rebel would be about the same as 200 ASA on film.
You can get incredibly good results at ISO400, and very good at 800. ISO1600
is usable as a last resort option (something like 800 ASA film) but at that
value you'll get some color clipping, especially in the reds.
So, Digital Rebel is twice as good as any film when it comes down to grain,
or to be precise - noise. Film grain and digital noise are nothing alike,
because high sensitivity film is well... grainy. But high ISO setting on
digital camera results as a pattern made of pixels that have different
colours then they're supposed to. For example, you shoot at a clean red
paper at ISO 1600 and get darker or greenish or bluish dots.
Anyway, there are powerful programs that eliminate digital noise (and do a
great job too) so you can stretch your options even further. I have 10D and
shooting at ISO800 is something I feel completely comfortable with... Not
somethnig I would do so easily a few years ago...
