As much as I love Perseus, I prefer to work with physical books. I've been looking to buy a lexicon as a reference when studying Greek, but I don't think buying a full edition of Liddell and Scott is entirely practical.
I've considered Autenrieth, which would be fine since I'm learning with the Iliad. The problem is that I've been doing a lot of work with Aristotle lately, and I like to throw in some Aeschylus in my free time, so a purely Homeric dictionary might not be good enough.
So, any suggestions? What do you guys use?
