One more vote for the RSV-CE (Revised Standard Version, Catholic Edition) also known as the Ignatius Bible. One caveat however, while the translation is wonderful, the bible itself is not of the best quality. It is printed like a low quality paperback. I have a copy, but if they were to ever release a version truly fit for the Word of God, I would be the first in line to buy another.
The New American Bible (NAB) is also a favorite of mine. While the translation is not as good, there are footnotes, and it is a beautiful Bible.
Finally, you cannot go wrong with the Douay-Rheims translation.
