For the non-instant camera enthusiast is the Kodak Instamatic X-15, which was introduced earlier this year. It can be bought, at the Walgreens camera & photo department, for just $21.00.

The X-15 takes a 126 film cartridge. You just open the package, flip open the back of the camera and snap it in. It's SO much easier than threading a roll of film into the camera (as everyone did just a few years ago).

For night and interior shots, the Kodak camera buff will also need a pack of Sylvania Blue Dot Magicubes. Unlike regular Flashcubes, they do not require the camera to have a battery. In keeping with today's disposable society, you just pitch the spent Magicube after taking four flash pictures.
