30D is a fine camera
and so are many others really.
I think share with us what your needs are.
what sort of photogaphy do you like doing.
Do you need speed? do you want to do more wildlife, more portait?
What lenses did you have in mind.
Dont spend bulk of your money on a 30D if your planning to buy crappy lenses.Always consider glass before the body.
So as you can see it there is more to your question really.
