What you are trying to look for is a Polaroid Instant camera wherein after taking picture then it will print automatically from such camera. I found lots of Polaroid cameras at Amazon. Like this cool Polaroid One600 Classic Instant Camera for $179.36. It has focus-free lens for great shots as close as 3 feet with autoflash that helps to illuminate pictures in any light. It has digital LCD picture counter and feature setting display. This one uses Polaroid 600 instant film.

Check this used POLAROID AUTOFOCUS 660 Instant 600 Land Camera w/ film with current bid of $18.99. You can find this at Ebay . This rare POLAROID AUTOFOCUS 660 camera with black shoulder strap features AF/Automatic Focus and Built-in Automatic Flash. It uses 600 or 770 instant film and is in very good condition and works great, comes with old film still loaded in the camera.

If you will buy any of these cameras then you will need Polaroid 600 Instant Film Single Pack (10 Pictures) for $18.95. It has 10 exposures and develops in approximately 3 minutes at room temperature with balanced for daylight and electronic flash exposure. ISO 640/DIN 29 film speed that works with all 600 cameras.
