It sucks to pay for a data recovery program, but hey, when you need it you need it. Someone pressed "format" on our Sony camera and bang, all the photos were gone. I tried Boomerang, Exif Untrasher, FileSalvage, Image Rescue, PhotoRescue, and StellarPhoenix. Although StellarPhoenix WAS able to find the photos, it's interface is much less elegant, and it costs about 8x more. Although it took over an hour and a half to scan my 4 GB CF card (1.42 G4 Mac Mini), it works great. It even names the files in order of the date they were taken. What can I say, it works great and was DEFINITELY worth the $20. And, they apparently give updates for life (although it works perfectly now so I don't see what they could upgrade other than new OS X version compatibility.)
