Saw an add for the DeckJig in the Family Handyman... Happened to be in woodcraft last night and was pleasantly surprised to see it on the shelf.
I am adding on to our deck and wanted a concealed fastener system... This looked to fit the bill. Only concern now... I do my deck boards at 45 degrees. Being that it has the two 45 degree drill ports I figured that would be the way to go... the video that comes with the unit still suggests using the center hole though.... weird.
