Bushnell offers a two year manufactures warranty, while most others offer only one year. You can find several good buys on EBay but make sure the seller is an authorized dealer by the manufacture or there is no warranty.
I have seven of the 2009 Bushnell Trophy Trail cameras and have had good performance. I also am using Moultrie D55 IR, Moultrie M100, Moultrie M80XT and Moultrie 880.
My preference is video. The Bushnells that I have, when set to video, this is all they will take. Most Moultries, when set to video will take a picture first, then the video. What is captured in the picture may be missed in the video.
Some of the newer cameras when set to video take high definition which is like viewing a high definition video on an older model TV. You have the black band at the top and bottom of the video. Taking videos of say deer, when they are closer, you may cut off the head and feet.
Newer cameras also require top quality batteries as around 1.3 volt these cameras start to malfunction. Older models, the voltage could drop to 1.0 to 1.2 volt before this happens.
Two good quality batteries I have been using are Duracell Copper Top which test out at 1.60 volt using a digital meter. The other brand is Ultimate Lithium which are available in 9X and test 1.79 to 1.83 volt using a digital meter. These batteries are more expensive but have excellent performance in cold weather. I have taken videos at a -32 degree Fahrenheit with the Lithium.
As for rechargeables, in my opinion are not suitable for trail cameras because you can not obtain the required voltage one needs for trail cameras to perform properly for an extended time.
A suitable price for a good camera is $150. to $200. range. Cheaper cameras have cheaper quality parts, this is why they are cheaper.
Good luck in your choice.
