It was rather disappointing to find that in the "Joint Association of Classical Teachers, Reading Greek" series, which is otherwise so good, that they have used such a small type face for the grammar. I might look at the "Athenaze" book. Might as well completely trash my bank account!
I have printed out some of the Textkit books with the pages set to a full A4 size and double sided the paper, that's not too bad but sometimes the old metal type printing wasn't very clear to start off with, so all you do is enlarge the blobs and blotches. The Pharr is a good (or do I mean bad!) example of this.
Apart from this, it's only taken me about 2 weeks to learn to read the Greek alphabet reasonable well, so maybe there is something to be said for squinting at it through a magnifier. What did someone say about no pain no gain.....?
