I got a Cuddeback this year and have been very pleased with it. The pictures are great in the day time and night time. I am having problems with the video mode but I haven't had a lot of time to play with it yet. It does not have a built in display to view the pictures. It uses a flash card for memory. I have a digital camera that uses the same card so I just put it in my camera to view the pictures. You can buy a cheap hand held tv that plugs into the Cuddeback to view the pictures also. There is also a firewire to connect to your pc. I have a flash card reader that I use to copy pictures to my pc with so I can just swap memory cards and leave the Cuddeback in the woods. In advanced mode there is a battery meter. Mine was in the woods for 2 weeks and it was still reading 3 bars, 4 being max.
As far as tips, I think I'm going to buy a small tv so I can see what it's aimed at better when setting it up. Make sure you use the torx screw and lock that thing up. I had my Stealth Cam stolen. No big deal cause it was a POS.
Hope this helps with your decision.
