Good Overflow Box?

[RyanMcLaughlin]

I have a 100 gallon tank and am gettting a 20 gallon sump. What is a good overflow box to get?

Without a doubt a Lifereef, they wont fail on you, I had seen the cheap ones and in time they will fail usually when power goes out then comes on, OOOPS water overflowed all over, with lifereef this wont happen, there kind of pricy though.

I bought the eShopps box with two 1" overflow pipes (very inexpensive). It never breaks the siphon once you start it, but the standpipes are incredibly noisy. I built a custom standpipe though and now it runs nearly silent. Even so, I'm going to have my tank drilled instead when I break it down here soon.
