When all is said and done, however, I like to take the individual verses out of context as much as I can. It's more fun that way. I like a book that tells me there's no better way to spend my time than eating and drinking!
My own notes on Ecclesiastes are online at Studies in Ecclesiastes on my webpage. It is a series I taught following the death of my father about 10 years ago. It is interesting how that sort of event gives one a new paradigm on life and death.
To put a further plug in for Edward Reynolds (Spurgeon says "he is always good" and Reynolds ranks #14 on Tony Reinke's Puritan Library Recommendations), one can either get the complete English Annotations, or get Vol. 4 of Reynolds' Works for $22.00 via Abebooks (as of this evening), or download for free his Works, including his commentary on Ecclesiastes, at http://books.google.com/
Ernst Wilhelm Hengstenberg's commentary on Ecclesiastes is also recommended by Spurgeon and, although not online as far as I can tell, is available at Amazon for $21.00.
