I use one from CPR http://www.marinedepot.com/a_of.asp for my 2" tank and it is working fine. There is a possibility that the siphon might fail and flood the house. A venturi powerhead is required for this design to keep the siphon working in case power failure.

You would have better sleep at night to get a tank with built-in internal overflow if possible. I use the overflow box as temporary solution till my new tank is cycled finish.

...here's mine in action.... basically, when ur return pump stops to function, the overflow will stop as well, but it will retain the siphon back as soon as water starts pumping again in the main tank....

Wow, thx man, reefer guy, for showing me the pics

can provide further info??? It looks bulky. Does it have a powerhead? Do u put any filter media in an overflow box, or izit juz simply to pump water down into yr sump? Can tell wat brand n how much or not?

Tis may seem a stupid question why do u use an overflow box huh?

it doesnt have a power head, it is just self priming and will continue pour out water as much as it can suck out of the main tank. if in case the sump pump that brings in water to main tank fails or stops for any reason, the overflow box will stop coz there aint no water to prim..... its not really that bulky, just needed 7cm of free space behind the tank, as for me i put it on the shorter side coz my tank is 3-sided....no filter media at all, just down the sump thingy....

y i used overflow box? simply bcos i dont have a bottom drain in my main tank, and its more spacious in a sense, aside from i can reposition it wherever i want if i need more space in a certain area...

i did advertise for these before, had a few shipped from the US last month, seems noone is interested... anyway, check this web and let me know if u r interested....
