Greg,

I have been very lucky to be in a position to try out several different trail cams. To be honest CuddyBack might be the best out there. But don't be suckered in by infraRed cams. I have seen deer spoke from those going off too. I was explained to that it still makes a high pitched sound when it goes off and can spook deer.
As for checking your cams without scenting up your woods, I came across a camera that I have set up in MO, OH, and TX. That I can check at anytime I want through the internet. It is called Smart Scouter, they have many options one being view photos through the web to a live feed. I think it is neat, haven't had to many problems, but than again I just got them.
