The precision port is from Blue Water Photo (in California) and was $499. There is a good review for it at Panasonic 8mm fisheye & Precision Dome port |Underwater Photography Guide
The only issue is they had to do a slight modification to my port for it to work so I had to lose my "somewhat useless" focus lights on the front of the PT-EP05L port. I use a focus light in the hot shoe so it wasn't an issue. I love the fisheye!!!
