Searched for "Hexapla" and was surprised to find that this is not already available from Logos. Not sure if there is a better version available or not, but this edition by Frederick Fields was published in 1875 and therefore should be public domain. The Hexapla would be a perfect resource to have show up in the Exegetical Guide. From what I can tell, neither Accordance nor BibleWorks offers the Hexpla, so this could potentially be a unique resource that might help Faithlife attract customers interested in textual criticism.
