I use a trailmac digital and have had pretty good results. Camtrakker and others also make digitals. After using the digital it is almost torture to use film again. The money saved on film and prosessing adds up fast. Most commercially made digitals are from $500 to $650. Some are less but if you want pictures to print off you would want a 2 MP camera at least, the cheaper ones are well under that, except for some homemade ones. My trailmac has a 2 mp olympus camera that takes good pics and the batteries last months not weeks.
