I'm no expert on the efficiency or prices on various skimmers, but Andy builds very high quality very efficient skimmers at a price that seems lower than most everything comparable. I cannot imagine anyone needing or even finding anything that is better made or effective. Being here in Houston, I am familiar with the Precision Marine products. I have heard they are quite good, but I can say that from what I have seen, they are less well made, and certainly far more expensive. To be honest, i've never really understood them. They saturated the Houston area markets so that even when everyone was into ETS and other high end skimmers, the only thing in our stores were these crappy expensive venturi and counter-current Precision Marine products. The company certainly seems to have grown a lot, and come up with current designs that appear and are reported to be quite efficient. But, I still wouldn't pay the price being asked as I don;t see anything that puts them at an adavantage over other premium skimmers, and definitely not compared to someone like My Reef Creations who, as far as I can tell, gies you the best of all scenarios.
