Buck Magnet - I have the Cuddeback. The pictures are decent and overall I am happy with it. I am currently getting materials to build my own for my next one. I do not know much about the other 3 but I will tell you this about the cuddeback. It has 2 security codes you can set. Without these codes the camera is useless. You set one 5 digit code of accessing the pictures and the other 5 digit code is the master code. With the master code you can set owners name which appears on all pictures. That was a big factor in my decision to get this camera. Just my 2 cents. Good luck with whatever you get. I'm sure they all will do a decent job.
