check the DIY / Products section - there's also loads online. The choice of most is pre-drilled and it seems most efficient otherwise you end up with a weir which hangs on the display tank negating one of the reasons for having the sump (Equipment hiding)
just my opinion but in your situation i would look at replacing the hose on the pre-drilled holes to something more asthetically pleasing.
