I have been using Stealth cam for several years, and every year, at least one craps out on me. Now I see that they have reduced their warranty to 3 months, which just tells me that they know their camers are going to bite the dust. Friends that have the Moultries are telling me they work pretty good, but they have a tendency to "go to sleep" if in standby too long. On chasingame.com, I see that the fellows there are bragging on the new Scout Guard 550, and have bought one to try. It is about the size of your hand, runs off 8 AA batteries and suppose to last 80 days. It is an IR model. It also uses a remote for programming, and you can use a 6 volt external battery. Anyone of you guys used this one?
