What is a good brand overflow and return pump

[marciemp]

I am looking for a hang on back overflow for our 92 gallon corner tank. What is a good brand, and what rating/flow? It needs to be relatively quiet as the tank is in our great room where I spend all day with the kids. And what size and type of pump would you recommend for the return then? The sump will be under the tank, and the height of the tank and stand is about 5 feet. Will probably use some sort of flexible PVC. The only other flow we will have is 2 vortech's.
Thanks,
Marcie
