Lamsa's translation is a really good translation (which I personally recommend), but instead of translating literally in some places, he instead translates with his interpretation of the word/idiom. He sometimes translates
daywah and
daywana as "insane" or "lunatic", rather than "demon" and "demon possessed", but this only happens a few times in the Gospels and Acts (he sometimes translates it as "demon" and "demon possessed" also). He also uses King James Version and New King James Version style, which isn't that much of a problem. Sometimes he uses Greek readings, but this isn't very common. His translation of the Tanakh is really good, and I read a lot of the Old Testament in the Lamsa Bible. There are a few strange readings:
"And you, Bethlehem Ephratah, though you are little among the thousands of towns of Judah, yet out of you shall come forth a ruler to govern Israel; whose goings forth have
been predicted from of old, from eternity."- Micah 5:2, The Lamsa Bible
"But as one of them was felling a beam, the axehead fell into the water; and he cried and said, I beseech you, my lord! it was borrowed by your servant. And the prophet of God said to him, Where did it fall? And he showed him the place. And he cut off a stick and thrust it in there; and
it stuck in the hole of the axehead. And he said, Take it up to you. And he put out his hand and took it."- II Kings 6:5-7, The Lamsa Bible
Janet Magiera's translation (both the original and Messianic Version) come highly recommended, along with her interlinear. The Way International's Aramaic-English Interlinear New Testament is also great! My personal favorite Aramaic to English New Testament translation is Andrew Gabriel Roth's Aramaic English New Testament, but it also has a couple of places with theological bias. David Bauscher's The Original Aramaic New Testament in Plain English and The Aramaic-English Interlinear New Testament are also very good.
Also take a look at the translations by James Murdock and John Wesley Etheridge at
