Best value?
Well, I guess that depends on what you are looking for as far as functionality.
Do you want fast trigger speeds?
Do you want Infra-red night shots?
Do you care about battery life?
How much are you willing to spend?
You want a homebrew or a manufactured camera?
Lots of factors to consider and lots of good cameras out there right now.
Usually price will go hand in hand with functionality.
Cuddeback, Leaf River, and Moultrie are all making a good digital now.
