If you enjoy the apostolic fathers, there's TWO community pricing resources that you WILL enjoy (and were previously mentioned on other threads as well):
Classic Studies on the Apostolic Fathers (29 vols.) Current bid: $30
by 21 authors 14 publishers |1849–1920
http://www.logos.com/product/27506/classic-studies-on-the-apostolic-fathers
Just the J.B.Lightfoot volumes would be worth your CP bid. They're frequently mentioned, when you read more current AF volumes. Indeed the newer volumes just ASSUME you have Lightfoot! These have a considerable amount of depth and you DO need Lightfoot.
In addition, you'll notice quite a number of volumes on the 'odd' AF's. The 'Twelve Apostles' catches my eye. Then also Kirsop Lake's Mount Asos facsimiles on Hermas, which if I'm not mistaken were rescued out of Egypt. Complements the Sinaiticus segment. And MANY more!
Text and Studies: Contributions to Biblical and Patristic Literature (29 vols.) Current bid: $50 (with $40 nearby)
by 21 authors Cambridge University Press |1891–1922

These books are similarly invaluable, filling in where you're 'running out of juice' in your main library. Fragments of Heracleon, Ephraim's Quotations, Athanasian Creed & Early Commentaries, Odes of Solomon, etc. It's REALLY extensive. Just two or three of these will pay for your bid. You certainly don't want to miss out, and then see what Janie will price them, on the breakout later!
Take a look ... you'll be impressed.
