WTB Overflow kit

[Subliminal]

I have an old Oceanic 30g cube I'd like to drill and set up an overflow.

Looking for an overflow setup of some sort. Would really like the Modular Marine setup, but it costs 3x what I paid for the tank.

Looking for something with at least 2 outlets (1/2 to 1 inch is fine)

Looking in the range of 400-1200 GPH

I'm in NJ, but would be more than happy to pay shipping.

Thanks!
