ESV Study Bible
From earlier previews of the maps, illustrations, and study notes, I think that the ESV Study Bible will be a very useful resource for those interested in biblical geography and archaeology. The Bible includes more than 200 full-color maps, and 40 stunning, up-to-date illustrations. (For one example of "up-to-date," look at the Pool of Siloam on the Jerusalem illustrations.)
The Bible is due out on October 15, but the publisher wants everyone to know just how good this Bible will be before then. To that end, they have just begun a blog. I'd draw your attention to the post on the Gamla synagogue, with its outstanding reconstruction drawing (which you can download in high resolution). Leen Ritmeyer gives his perspective on the illustration he helped to create here.
If you want to know more about the Bible, there's a 5-minute video overview that shows off some of the beautiful illustrations.
One thing that I don't think I'll ever understand is how books like this can be so affordable ($31.50 online).
