I have a moultrie I-40 and love it($200)., I dont like a flash on a game camera. IR will catch more animals than flash will. I saw some study that had 40% more pics from IR vs. Flash(dont ask, I have no clue where I read that). Battery life is also MUCH longer with IR, The I-40 claims 150 days, mines been about 3 1/2 months on the same batteries. +1 about cheap is ok for feeders. The fast triggers are needed for trail cameras, but at feeders the deer should stick around and smile for you. Another thing, with IR moving pics at night dont always turn out great(a few look like ghosts), so the flash cameras get the nod on that.
FWIW, I hear GREAT things about the scoutguard550, dont have one, but will next year. I think they run about $200 also.
