Try this site if you want to check the pricing for one the size you are looking for. I have been very impressed with the asm g3 that I'm running. I also very much like the becket skimmers, I've just found that the needle wheel pump skimmers use much smaller rated pumps(less cost to run) and the pumps themselves cost less than a good pressure rated pump for the becket skimmer, plus less adjustments required. Oh and the asm, euroreef, turbofloater come with the pump included.

There are many other online sites carrying these now like premiumaquatics also. I just like this site because of all the parts you can buy seperately and the prices are as cheap as any.
