Can anyone offer me some advice on cameras? I can potentially get a Canon EOS 40D 10.1 for around $400, brand new. I'm not a serious photographer but I take enough pictures that I get frustrated using point and shoot type cameras. Any pros or cons about this camera I should know about? How are we feeling about compact flash cards these days? Any other DSLRs that I should be looking at instead of this one? Thanks in advance for any replies.
