I made one myself out of acrylic. The cpr ones are bad and I know a few people that have had their tank overflow because of this crappy overflow.
The lifereef one is much better and this is the one that I kinda coppied for the one I made.
Go with the lifereef, or marineland tidepool overflow is another good one.
