Good to hear on the G40. I think that is where I will be headed, if ever (when, I suppose) my current Anvil Foundry gives out. A neighbor had the first generation Grainfather and his only gripe (and it was slight) was the slow-ish timing from mash to achieve a boil. With the new 220V/3300 watt element on the G-40, it looks like it has the best of all worlds. The S-40 would probably be my choice, but only because I generally want fully hands on brewing (which, of course, is available on the G-40, but then why pay the higher price for the automation aspects....) The point is the improvements made over the last few years really make these new systems quite dependable and fun to brew with! If I was starting out new right now, I would not hesitate to jump into any one of the major makers' products.
