Tree Field Guide Recommendations (1 Viewer)

I'm wondering if anyone has any recommendations for a tree identification field guide for North America. In particular, I'm interested if anyone has had experience using the National Audubon Society Field Guide to Trees (Eastern Region), Golden Field Guides: Trees of North America, and/or Peterson Field Guides -- A Field Guide to Trees and Shrubs: Northeastern and North-Central United States and Southeastern and South-Central Canada. I hear good reviews of the Audubon Guide online, but in my experience other Audubon guides are not particularly helpful.

Thanks in advance!
