Looking at purchasing another trail cam, what are some of the better ones?

It's all going to depend on how much you want to spend. I bought a Moultrie m-100 and it is by far the best I have used in it's price range. The picture quality and clarity is top notch. Night pictures are excellent as well. Its small and compact and runs off of 4 or 8 AA batteries and I've had it out for over a month an it still had tons of battery left. My favorite part is that it comes with a built in viewer. I saw it at bass pro for $219 but I bought it from amazon for 149.99.
