Please let me know what resources you think are the best that Logos offers.
A good place to start is the SESB 3, which contains apparatuses for the NA27, BHS, BHQ fascicles, Rahlfs Septuagint and the Vulgate.

Metzger's Textual Commentary is a nice addition for the NA27.

Tischendorf's Apparatus is fairly old, so it doesn't contain the newer textual discoveries, but it's a larger apparatus than the NA27's, containing many readings that the NA27 editors didn't include: http://www.logos.com/products/details/1775
The New Testament Textual Criticism Collection includes some fine books:

The Biblical Languages: Reference Grammars and Introductions Collection (http://www.logos.com/products/prepub/details/4679) includes Westcott's Introduction to the New Testament in the Original Greek as well as Swete's Introduction to the Old Testament in Greek, both of which are good reading and introduce the types of textual issues that folk digging into apparatuses should be aware of.
Some newer individual titles include:
Old Testament Textual Criticism: http://www.logos.com/products/details/3605
A Student's Guide to Textual Criticism of the Bible: http://www.logos.com/products/details/2970
Some older works on the subject are available (I haven't looked closely at either of these yet):
Nestle's Introduction to the Textual Criticism of the New Testament: http://www.logos.com/products/prepub/details/6424
Warfield's An Introduction to the Textual Criticism of the New Testament: http://www.logos.com/ebooks/details/INTROTXTCRTNT
If you're interested in the LXX, Tov's alignment between the LXX and the Hebrew/Aramaic scriptures includes many notes on the translation and reconstructions of what the LXX translators might have been looking at: http://www.logos.com/products/details/1785
My favorite Text Criticism book NOT found in Logos (at least yet) is Tov's Textual Criticism of the Hebrew Bible. Wurthwein's Text of the Old Testament would be my second choice, and Aland and Aland's Text of the New Testament is also good (as is just about anything by Metzger on the subject).
Thank you for your post.
Yes thank you, that just added a couple of books to my library that I think will help me!
