Trail cameras are like anything in life - you get what you pay for.

There's plenty of cheap ones that will work and get you photos, but the amount of photos, quality of photos, and other factors such as battery life, trigger speed, etc are going to suffer. If you can live with that and be happy with any photos at all, go for it.

If you want something more that's going to trigger fast, give you good high-quality photos, and have good battery life amongst other features you're going to pay for it.

Right now I have a CamTrakker Digital Ranger, a Cuddeback Excite, a Stealth I450, and a Moultra 1.3 MP. They range in price from $450 to $100. The CamTrakker is the most expensive of the 4 units, but it takes the best quality photos and has the 2nd best trigger speed next to the Cuddeback. The Moultrie is a piece of junk, the batteries don't last more than 7 days, and it triggers very slow. However, for $100 it works great over a food source like an apple tree/mineral lick, or over a scrape.

In the end, it all comes down to personal preference in what you're looking for and what you're willing to pay.

Good luck with your decision, and post photos when you get them.
