For the cash I don't think you can go wrong. Easy to maintain, and set. Low noise, huge skimmate production. Do the gate valve mod for like $20 and it's a snap to adjust. I'd highly recommend it. Love mine. I've even got my LFS on board, they are running 3 of them and always looking for more. Because of that, they are selling a ton too. People see how they work, and the price, and jump on the band wagon.
