I would go with the XTi. The XT is a much older model and the technology has improved. As for what the previous answerer said I agree that eventually you will need everything he mentioned and more. I wouldn't worry to much about getting everything now. Get the kit lens and practice. Learn how to use everything on the camera. Figure out what it is you like to shoot then you will know better what you need.For starters you will need a UV filter for the kit lens, a couple CF cards and maybe a spare battery. As far as editing goes Photoshop CS3 is the best and if you can afford it that would be great but seeing as it cost about as much as your camera I would recommend you start out with Photoshop Elements 6. It can do most of what CS3 can do and only costs $100.00. CS3 is designed for professionals and advanced amateurs and will probably be overkill for you.Once you have figured everything out you can start buying additional lenses and equipment that will fit your style and interests.
