I found some for $130 each from... of all places... buried in with the dizzying array of bushings and high dollar motorsports items... Elephant Racing:
Elephant Racing | OEM Control Arms and Links | Porsche Boxster/Caymen
I just ordered them and they shipped out and should arrive 12/29.
I wonder who they are made by, I guess I will find out when they get here. I called and they said they were OEM Porsche, so $130 is a smoking deal if that is true.
