What am I missing?

I just bought:

Nikon D70 and Subal housing.

I already have:

Substrobe 100a

Sb 105

Sb 800

Nikon 105mm+port

Nikon 20mm+port

I still have a few dollars left.

Should I house the sb800? buy a pair of ds125s? buy a zoom lens and port? get a nixvue vista? upgrade to a suite? something I'm totally missing?

I am traveling to Bonaire in a few weeks and won't have an opportunity to test the new rig outside my bathtub, so any input is greatly appreciated.

Thanks,

Vladimir
