Port suggestions for L&M housing

I was thinking of upgrading to a housing for my digital camera. I have a Nikon D-100 and was think of investing in a L&M housing. Since I can;t afford to outfit my housing with everything off the bat I was wondering which port I should get. I will most likely be doing my next diving in Lembeh and thought macro lens and port. Any suggections for port or lenses?

I have both the dome and macro ports for my L&M D100 housing. Both are great. It just depends on what you feel like shooting. From what I've read about Lembeh it sounds like Macro would be the way to go. Keep in mind that you might also want to invest in the focus gears for your Macro port so that you can manually focus. That's an additional expense. Its' always something isn't it?

Have prices on the D100 housing started to drop yet? I would think that with the announcement of the D200 it is only a matter of time.
