I've used all kinds of cameras expensive and cheap. I have Moultries, Bushnell, and Wild game cams.
I have 6 CAMS on my property. One of my lower end cams is a Moultrie A-5. It does a great job for the money. Goto ebay. You can get the A-5 for $65 Free Shipping.
You can get into the game for under $100.
