DSLR question

Guys, can I assume there is absolutely no merit in the canon 10d over the 300d for astrophotography? The 10d has a higher film rating at 3200 but I'm led to believe its unusable astronomically. I'd be interested to know everyones opinions about other dslr brands, canon seems to rule the roost so to speak.

In short

"After owning the D60 for one year I decided to exchange it against the new 10D model.
The main reason for this decision has been the better noise behavior during long exposures of the 10D compared to the D60 (Review)

Some other short cuts of the D60 have been improved too:
* nearly complete elimination of the red amplifier glow at the right side of the image;
* higher ISO settings up to 1600 (3200 not really usable);
* higher review magnification of up to 10x for analyzing images via the internal display;
* improved remote capture software allows multiple interval exposures each max 30 sec (but no bulb mode!);

The new cheaper Canon Rebel (300D in Europe) supplied in a plastic case shows similar results for deep sky applications, 2 major drawbacks: no mirror lockup, no connection to remote interval timer posssible! "

I went with the 300D (mostly due to price) and am happy with it. The one thing I did notice is that it does not have the mirror lock while the 10D does. The 10D also has a more robust body.
