I got to brew with John on his new system with the new pumps last weekend at the BYO Boot Camp in Santa Rosa. The pumps were fantastic! whisper quiet compared to my chuggers and they are a breeze to clean up with the single tri-clamp holding the entire pump head together. The flow valve is simple to take apart and clean too. The head will be interchangeable with march and chuggers and he said they will eventually be available without the motor for around $100. The whole pump he said should sell for about $200. I was very impressed with them. He thought they'd be available in April sometime.
