Here's another book worth mentioning particularly because it is rather easy to read. I've included a rather lengthy [edited] excerpt in response to John's request.
A Student’s Guide to Textual Criticism of the Bible: Its History, Methods & Results [Amazon LINK] [Logos LINK]
by Paul D. Wegner, Downers Grove, IL: InterVarsity Press, 2006.
"The method used in this book is
reasoned eclecticism, wherein the New Testament text critic examines all available evidence, both external and internal, to determine the most plausible original reading of the text." [p. 240]
Strengths:
>Economical, concise and very readable
>Covers both Old and New Testament textual criticism
Weaknesses:
>Although it mentions Byzantine Priority and its most prominent proponents, it does not delve into its theory.
>Covers both Old and New Testament textual criticism
