I'm really confused.. do I just need a regular SD card? Been searching and they keep calling them by slightly different names and I'm confused. The other thing is.. how many GB's do I really need? What did you all start out with? I'm looking at a 4GB because 8GB just seems unnecessary. I don't see myself shooting hundreds of photos at any given time, so is 4 good? This is one department I definitely know nothing of.. Any input is appreciated! I have the Nikon D3000 on the way if the type of camera matters.
