I recently received in the mail a wide-margin edition of NA 27 (Nestle-Aland 27th edition). For those of you who know the Greek New Testament by color of the cover, it is the “blue” edition. Anyway, Christianbook.com (CBD) has them available for $19.99. The regular price is 59.95! There seems to be about a 2 inch margin on the outside and at least that at the bottom. If you like to write notes in your Greek NT, it is real benefit and you cannot beat the price.
