I'm currently searching for a pair of strobes for my Nauticam housing and I'm wondering if I should go for Inon Z-240ies or Sea & Sea YS-D2 (or alternatively YS-D1, although they are more difficult to find these days in Europe).
I'm slightly leaning towards the Inon Z-240 (Mark IV) as it can be used with fiber optic sync cords (whereas the YS-D2 would require 5-pin nikonos cords on Nauticam housing) and I read far more posts complaining about the quality of Sea & Sea flashes than Inon's flashes. The YS-D2 would be stronger than the Z-240 (32 vs. 24) but this advantage disappears when using the diffusor to achieve the same angle as the Z-240. So the advantage that remains are the more intuitive controls of the YS-D2.

I prefer the complete ready-to-shoot setup being sold as a whole but will also sell individual items (with those buyers preferred who buy more parts).
I recommend getting one Explorer Case (3818) when buying the housing as the foam is customized for the Housing + macro port + both flash units (without batteries) and offers protection. I have a second 3818 Explorer Case in which the 8" dome, arms & clamps, and battery packs fit. So best is getting both strobes, arms, housing and 8" dome with the two cases.
