I used a regular 1.0 GB SD (San Disk) from Wal-Mart,it was the best one for about $22.00 + tax,the other SD like the 156 MB will cost a little less....I set the camera on high resolution for the best quality pictures.The flash is very bright on the camera and the eyes BUG OUT on some of the pictures.There are so many different features on the camera that it takes a while to read up and learn all of them,picture quality is ok...not the best for what I expected.My cheaper and older Moultrie 35 mm trail camera took much better and quicker shutter speedpictures but all the batteries cost me a fortune.
