There is a grainfather on my local craigslist that I'm interested in. I'm usually a 5 gallon brewer so that part SHOULD work. I do make some heavy brews so maybe the grain bill would be to much? The price (used) is almost 1/2 price of what i see on line for a new one, even though I see some less expensive clones which may work just as good. It is 110, I wish it was 220 as i have it already in my garage. But still should be OK. The controller was upgraded to the bluetooth one, which I THINK is the latest. He says it is now like the grainfather connect. I can go see it Saturday morning. I'm wondering what you folks think about it. Good deal, Bad deal? Go get it or run away.
