I've been working through Pharr's commentary on the first six books of the Aeneid, and getting to the point where I'm looking for more to read. I'd like to finish out the second half of Aeneid, but Pharr doesn't cover those books, so I'm looking for recommendations on commentaries.
Desires: working online or from printouts isn't very satisfying, so I'd prefer a physical book. The price should be reasonable, and I'm very willing to purchase a used, out-of-print book. By reasonable price, I'm not willing to purchase one bound volume per book of the Aeneid at $30 each. However, this is a pretty labor-intensive endeavor, and it would be nice if the binding didn't fall apart after the first reading.
While I've made good progress with Pharr, I'm concerned that there is a bit too much hand-holding, and I'd like to see if I can work through the remaining books without the crutch of macrons, or every vocabulary word on the same page. If possible, I would prefer a commentary with the notes on the same or facing page as the text, because flipping back and forth is tedious.
So, I'm curious what others have used and what you've liked and disliked, and why. How much do different commentaries by the same publisher vary? And how do you select one?
