I want to buy a digital camera, you know, the on where you can take off the lens and put it back on so I need suggestion at what camera I should buy. I was thinking about Canon Digital Rebel because they sell it used on the eBay for cheap. Also, what kind of accessories and the extras should I get. I was thinking about a flash and I read somewhere that the "off shoe cord" makes the images with the flash really professional. What do you think?
