I don't think you need anything PCI with the specified PLX chip.

The PEX8311 has a description of:

   "8/16/32-bit, 66MHz, Local Bus to PCI Express Bridge"

I believe that is an equivalent, but still relatively expensive in
comparison to just a PHY chip.

Very true - they seem to have the board layout all right there from
their reference design development board.  Pretty nice!
