I've had problems with illegal hunters. I have had one camera stolen. I am looking for cheap used game cameras to use to catch them in the act. I have made steel boxes out of sheet metal and they work real well. If I use 35mm cameras even if they shoot the box the film is still usually ok.

I have a deer cam 35mm that I could sell for 40.00 plus shipping

Ebay I bought 2 for less than $25 plus $8 shipping.

EJ, Not that this helps you out now but last fall BASSPRO had stealth cams on sale for $35 ea. with a $10 rebate per camera (max 3-cam limit). I picked up (3) more for my collection. Sale is off now but you never know what the future holds.
As a side note: I have a stealth cam that died due to ant damage. I set it out opposite of a good camera and put a little flagging tape on it to tempt criminals, hope to catch them in the act with the good camera if you know what I mean. As they say, if I caught them, they'll never find the body.
