Mainly I'm looking for some buying advice. I don't have a camera yet but I've been doing a lot of research before I buy one to make sure I get the most for my money, and I want to make sure I get everything I need before buying a camera. I don't want any multi hundred necessities to pop up that I wasn't aware of. (I know I will be spending $$ forever on this) I just want to get my main rig to get going all at once. I'm pretty set on getting a Canon 40d. I plan to shoot a lot in raw and I was curious to what size memory card people recommend. If I'm doing my calculations correctly I'm only going to be able to get 9-10 shots per gigabyte in RAW? I will be doing mainly on site shooting Concerts/Extreme sports so dumping the files off is pretty much out of the question. What do you all recommend?
