Yeah don't get me wrong, I'm a firm believer in anything worth doing is worth doing to excess. I've been extract brewing for about 2 years now, and have been lurking the forums for quite some time. This was the first time I had seen this configuration, thought it was wonderful in it's simplicity.
I actually just finished gathering all of my equipment to do my first AG batch today, probably start in a few hours. Big thanks to everyone on the forums for all the great information, pretty much any question you can think of has been asked several times.
