Right now, I would have to recommend the Covert Black 60.  Although I believe the Moultries have improved dramatically, I'm worried about the audible "clunk" I've been hearing about when their IR filter arm moves over the camera's lens.  That's a very bad thing to have.  Deer hear it and avoid the camera.  In fact, I think audible filter-arm noise is worse than a visible flash when it comes to producing camera avoidance by deer.
