I have the T-7 and just do personal blades and those of close friends, but I absolutely love it. I'm usually too lazy to set up jigs and just free-hand lower valued blades that only need to have a good edge and get great results. After some practice, that is. Good luck with your new system, I thought the T-7's user manual was amazingly useful along with youtube videos and basic trial and error. My biggest mistake was trying to true up the stone too much and too often, ending up shortening the life of my stone. Otherwise it's almost idiot proof, in my (admittedly) limited experience. Hope you enjoy it and are able to get your money's worth, because that was the worst part for me.
