Funk's NT Greek grammar is one of the best. Funk was in the era just past structural linguistics. He was a linguist, though much of his life he spent promoting"The Jesus Seminar." In 1961, Funk translated and edited the 9th/10th edition of Blass//Debrunner's Grammatik des neutestamentlichen Griechisch.
Funk's Beginning-Intermediate grammar is different than the approach of most beginning grammars. I would say that the closest NT beginning grammar to Funk's NT grammar is James Swetnam's An Introduccton to the Study of New Testament Greek (PONTIFICIO ISTITUTO BIBLICO — ROMA 1998). Personally, I think those two grammars are the best comprehensive beginning grammars. Someone who wants to learn Greek via the "communicative method" needs to look at these grammars.
The B-Greek community, and especially Carl Conrad and Louis L Sorenson assisted the wife of Funk to re-introduce Funk's grammar.. After many edits,the B-Greek community digitizied and published Funk's grammar into an html format. This was the initial draft of Funk's grammar. This raw version can still be found at http://www.ibiblio.org/bgreek/project/funk-grammar/pre-alpha/. Carl Conrad (Ph.D) and Louis L. Sorenson went through the grammar from a new scan, and created a very accurate digital copy of the grammar -- having been proof-read over 20x. The result is that Polbridge Press has published this book in a print format. It can be found at CBD at https://www.christianbook.com/beginning-intermediate-grammar-of-hellenistic-greek/robert-funk/9781598151152/pd/151152
I think this would be a great addition to Logos' Koine Greek grammars.
