I too have had luck with the brownings in the $100 ~ $150 price range. I used to use the lower brands (stealth I think) but they are pretty much disposable after about 2 years. Only thing I don't like about my lower end brownings is they are red IR flash.....my next cam will be a black flash type....
If you like the idea of having them record video (I think the video tells me more than a simple pic) - make sure the cam will accept a larger capacity SD card. My Brownings will fill as 16G card in 2 weeks simply because daytime file size is 300,000K, nighttime is about 60,000K per file....if you have a lot of activity they may fill even sooner. If your doing pics....I still like the larger capacity in case the cam needs to sit a bit longer than normal for some reason....I hate the idea of missing something because a card is full!
