Best online resources for expository preaching

Every so often I share links to the best free online resources I've found for sermon preparation. Here are the ones I use week-in and week-out for help in preparing my own expository sermons and Bible studies:

• Bible.org. These studies, arranged by book of the Bible, are often insightful and helpful--especially the work of Bob Deffinbaugh. I don't recommend simply appropriating another man's lesson as one's own. But Mr. Deffinbaugh's work, as with others listed here, usually contains some good, sound ideas worth using with proper attribution.
• IVP commentaries. Sixteen NT commentaries are available online. While preaching through Philippians I've been blessed in using Gordon' Fee's commentary.
• Piper's Notes. Sermon texts from John Piper, arranged by biblical text.
• Ray Stedman's Expository Studies. Mr. Stedman had a tendency to not clearly separate biblical fact from speculation, but his observations are as a rule insightful and helpful.
• The Sword Project. Several Bible browsers and their modules are available free online for downloading. This one is my favorite.
• The Text This Week. This site offers resources for lectionary preaching, but the Scripture index is helpful for any expository preaching. The "Contemporary Commentary, Studies, and Exegesis" sections are especially rich and relevant.

There are many more that I use occasionally, but these are definitely the A-list. How about you--any links you'd like to share?
