30D:
Faster FPS
Larger Buffer
Better viewfinder
Rear Command Dial (VERY USEFUL)
Bigger Screen
Spot Meter
Black in color
Rebel XT:
Cheaper
Available in silver or black
Lighter
Both camera are capable of equally good image if can get them to meter correctly and AF correctly. The Rebel is slighltly inferior in handling because of the lack of the rear command dial, darker viewfiner and slow FPS. So if you do not need this feature, save teh money and get the rebel. If you THINK you need this features, ask yourself if you are shooting sports? If not, you do NOT need the 30D but it does not mean that you should not consider it. The 30D is a very good value and for some people, the extra features are worth the extra cash. If i were in your position and have the same passion for photography as i do now, I would go for the 30D because i will appreciate the extra features. BUT if getting the 30D means getting a lousy lens, it is not a very smart move.
