I was going to get one but decided on a DC pump. My pump comes tomorrow and I'm super exited to get it installed. BRS now sells the speedwave DC pumps and has them in stock. Take a look.
I've been using my Speedwave DC pump for over a week now. I highly recommend it or one of the other DC pumps. With 6 different speeds its amazing to be able to control the flow. 10 minute feed button and it is super quiet. BRS has them in stock when others do not buy say they do.
