You know, I've also had troubles searching the Niagara website.
That link just came up with a global Google search. But, in the past, I've specifically searched the Niagara site using Google.
For example, Niagara has several 40h and 48h hubs for sale (black and silver), but they are almost impossible to find unless one knows exactly what one is looking for.
Send me a PM if you wish to do a 2-way or 3-way split of a box.
