Inon lenses - where to buy?

I am planning a trip to the flower gardens on the 4th and would like to purchase an Inon UWL-100 and possibly the UCL-300 lenses. However, I can only fine two places online which sell them - underwaterdigital.net, and marinecamera.com. Both have competitative prices, but man, these lenses are expensive. Does anyone else have any other sites or stores where these lenses can be purchased? I'm looking for a possible "package deal," for both lenses.

I would LOVE to get the inon dome port for the UWL-100 as well, but alas I cannot justify spending another $350 at the moment on TOP of the $500+ this is going to cost me.

The close up lens correct model number is UCL-330.

When you consider a Nikonos 15 mm lens is about $1500 or Sea and Sea 15 mm lens is $1000, the UWL-100 plus dome port has a pretty good price/performance ratio.

Cheers,
