I agree with PJ. and Lead, I when I bought My-80 cams I didnt see any features to justify the difference in price. Like lead I have no nead for a picture viewer I just switch cards out and get out of the area.
As far as SD cards I only use Sandisk 2gb (class 2) cards. They are only $6.20 each and I need alot of them and since I never go more than 6 weeks between cam checks and the fact that I never had a 2gb. card full when I check my cams (even when I running my feeders) there is just no need for me to buy more expensive cards. Actually I dont think I have had a 1 gb. card filled up when I use to use them. Pike
