they aren't to exspensive. depends what type you get. cuddieback, moultrie, stealthcam are great ones. wild game inovations is an ok brand, if you buy one get the i series..they are better. ive gotten 1000s of pics...deer, coons, hawks, buzzards, foxes. you just never know what was lurkin around. my brother got some of a black bear in our food plot (funny, the county officals screamed there were no bears here it was to built up and safe! lol wildlife adapts and WE are the ones that must learn to live with em.) a scout 7 will run you around 100 and a good moultrie m80 for 140. the cards you can buy for 15 to 30 depending on what size you want. if you really want to get into it you can get solar packs and wireless transmitters so even when it takes a picture it will send to your phone or computer (cool right?!)
