I literally just got my Vreg block from Nate today, looks amazing cant wait to get it in and running. Then I saw your post and thought, "damnit, I want one too". Ive been searching for a 680 classy block for a while as well and havent found anything but universal blocks (boooooo). If your up to the challenge nate I'd strongly consider getting one as well. Especially since the 800 series is now projected to "2015 sometime"
