I currently have a Fuji S5000 and I have been working alot with the manual controls rather than the auto. I feel that I am ready for a D-SLR, but I do not have a bunch of $ to spend. I looked at the Rebel and it seems to be a great camera in all of the reviews and comments. Please give me advice on what to look for. I know that mega-pixels are important but is that all that I need to be concerned about?
