If you decide to drill your tank, check out ModularMarine. You can order them from their website directly or you can buy it over on EvilBay. I've been using one for close to 6 months now and its great. They can also customize them for you any which way (most of the time for free). I highly recommend them.
Ive used the Eshopps Eclipse slim overflow before and I didn't care for it for two reasons: One being its noisy, and two the stated gph rating is exaggerated.
