Roundbal, I can pretty much assure you...you will not be dissapointed with the Tiny D model. I have not messed with any of the other cameras they make, but have been very impressed with this little beauty. If I had the money I would not hesitate to buy more of them.
Having said that, I just today bought a Covert Black 90. This is also a relatively inexpensive trail camera and has some great features. Probably the best thing is the black light deal. It does absolutely nothing when it takes a picture or video. But this little spypoint camera has some features that I really wish the covert had. The Black 90 is pretty new...so I'll post about it in a few weeks after I have tested it enough.
