RE: I-6.0 v I-4.0
I have 2 i-60's and an i-40. my next cam is definitely an i-40 unless i find a good deal on a 60 in the cabelas bargain cave.
really the only difference that is noticeable to me is the viewing screen which I only use occasionally and is so small that it really isn't valuable. the remote is a joke. I threw my second remote away when I took it out of the box. I can't tell the difference in picture quality between the two. oh, i've never once even looked at the barometric pressure on the picture.
