I've just been watching an instructional video about the Williams Warn at . I must say, it does look the part. It's very bling and I bet you get cracking beer out of it. However, price aside, I don't think it would be for me even if I could afford to throw $4-5k at it. It doesn't seem to resemble brewing/fermentation that I recognise. I'm sure it's not as tricky or as involved as the video suggests but it does seem both tricky and involved. I'm curious as to why you'd want to keg if this thing delivers beer as the video shows with a built in kegerator? I guess it's just another option for how you serve your beer.
Interesting tech/gadget product, far far far out of my budget, can't imagine it would give me better beer than I'm making at the moment. Good on ya to those who have one and enjoy it.
