Who makes the best external overflow??

As much as i would like just buy a bigger tank that is drilled and has overflows its not gonna happen anytime soon.  The overflow i currently have hooked up sucks and i'm having a hard time sleeping at night knowing that it is the only thing keeping a couple hundred gallons of water on floor.

 

I am looking into the lifereef ones, ive always used the CPR style with the aqualifter in the past and have never really had much of a problem with them. There are a couple problems with the one i have currently, the first is the nipple the syphon hose connects too is broken off so i just have a piece of airline tubing glued in the hole, the second problem is, my canopy is screwed to the wall and there isnt anyway to get the overflow off the tank without either taking down the canopy or hacking it up a little so i can get the overflow off. I was able to give it a fairly decent cleaning with a turkey baster and a dowel, i can't believe how much crap was trapped in there. After cleaning it seems to be working a lot better so i think it should be ok, i think rather than spending anymore money on this tank i am going to start saving up for a new one. I would really like a 84" x 36" x 24" tank with built in dual overflows. Until i can afford one of those i just need to make the current tank work.
