I have the Foundry 10.5 gallon and like it. It is a hands on brewing system - the only timer function is the preheating of the strike water (I preheat over night and set the timer to start an hour before I wake. I use 240V in my garage, 120V in my kitchen. I rarely recirculate any more - just stir periodically during the mash and sometimes lift the basket to get some additional recirculation with the liquid outside of the malt pipe. I use 50% power once mashed in at 240V, so the cycling is slower for maintaining the temperature set point without overshooting (100% power at 110V usually). I get to a boil plenty quickly at 240V, but don't have a problem with 110 V taking a bit longer. I haven't had any service needs, so I can't speak to that, other than as a Blichmann-related business, I would expect great service.
My neighbor has the Grainfather and he likes it, especially since he bought the neoprene jacket (helps get up to temp a little quicker and holds temp better in his opinion). He likes the counterflow chiller, that came with the unit, but now that they make superfast immersion chillers for all of these units (Jaded, CuSS, etc..), you can go with that version as an add on, if you would like. The Grainfather definitely has more bells and whistles and sounds like it has great service in those rare instances where service is needed. I brewed side by side with my neighbor and the Grainfather is definitely able to outperform some others, at least in terms of setting it up and letting it go through its paces automatically.
Durability is the one thing I was concerned about in buying an all in one - the heating element replacement being a critical key here. It sounds like most of the brands have the low watt element aspect dialed in for long haul use. I don't know how many others have exposed elements in their design (Brew Tools comes to mind, but is very expensive) nor whether the internally placed elements are replaceable for the Foundry and Grainfather. Likewise as to internal pumps vs. external pumps. Ultimately, make a list for side by side by side comparison of your key product attributes and make a decision based on the one that meets your expectations the best. Any of the well made versions will make beer well and last a long while, one would hope.
Cheers and good luck!
