Nikon has a great online support system for using their cameras. It's a good way of getting the feel of the camera before you buy one, but it is also very helpful once you have one. The link below is the Digitutor for the D3200.

Once someone decides to purchase a camera, the next step is finding a reliable retailer to buy one from. There are so many companies that do bait and switch and are really disreputable. Amazon is always good, but I always buy from buydig.com and B&H is also great. I'd check resellerratings.com before I bought from any stores. Sales people in most stores except for reputable camera stores rarely know much about cameras or photography, and their information is often very unreliable. I still think it's important to hold a camera in your hand to see what feels right for you and from there I'd pick a manufacturer. I love Nikon's colors, ergonomics, and reliability but the Canons and other manufacturers also make great cameras.
