Schultzy,
If I had any complaints about my Reconyx, it would be the night-time pics. They always seem a little grainy to me. I did go to their website to see if this issue is addressed. They recommend using either lithium batteries or rechargables. They do not recommend using alkalines. I was actually in Wally-World yesterday looking at these batteries. It seems to me the cheaper way to go would be the recharchables. The initial cost is greater, about $100.00 for two sets of batteries and the charger, but in the long run, it would be a lot cheaper than buying lithiums everytime you switched batteries. They say this improves the IR pics. Also, I think there is a software update available on their website that deals with this issue, you might check it out. Hope this helps.
Blessings.....Pastorjim
