It looks like it would brew good beer very cheaply. (start with 2-row American pale malt, and use a lot of it plus whatever caramel malt floats your boat. Buy the pale malt in 50# bags) But you would never recover the initial investment, plus it's so automated it takes all the fun out of brewing.
I would use a contraption like that if I designed and built it myself -- then the "art" would be the machine itself and the beer would be the payoff. I would also use it if I could buy a used one for $100. Since neither of those will ever happen, I will stick with spaghetti-cooker lauter tun, giant stockpot, homemade copper wort chiller, carboys, etc.
