RSV is my main study bible, but I will use all of them sometimes to shed light.

This is a reworking of the ASV, using the Byzantine Majority Text as its stanardized text, which is cool, I think.
The NET bible (which has lots of translators notes and is elegantly worded, although I don't always agree with their decisions on interpreting)

Thanks! I'm not usually at the computer - more likely on the sofa feeding the baby.
Where do you get your side by side tanslations of the Bible? D-R and Vulgate, correct?
