Matthew Henry's Commentary on the Whole Bible: Complete and Unabridged. Hendrickson, 2005.
It might take some digging to find the gems in each passage, but it's worth it. Beautiful commentary.
1 & 2 Thessalonians. IVPNTC. InterVarsity Press, 2003.
G.K. Beale is excellent. His exposition through the lens of "already not yet" eschatology is so well done.
1 and 2 Thessalonians. TNTC. InterVarsity Press, 1984.
Leon Morris is great, he fits a lot into the concise format of TNTC.
Arnold, Clinton E. ed. Galatians. ZECNT. Zondervan, 2010.
Excellent commentary. Love the ZECNT layout. Schreiner takes a Southern Galatian view on the timeline.
