Ardy, Here, the YS-1 and the S2000 are roughly the same price, add $100 and you can get a D2000, add another $100 and you can get a YS110a. So a S2000 is $400+, while a YS110a is $600 plus (closer to $700)
As light drop off is a square factor (it takes 4 times the light to go twice as far, close numbers don't mean much of a difference.
I used to use honeywell strobes in housings...huge, you could kill a seal with, strobes, they would light about 50% farther than the current S2000 will.
The cave images....three ways to do them. You can use optically triggered slaves (but they have to be close enough to each other to "see" the closest one (sort of chain setup), you can use fiber optic cable (just buy a spool of the stuff), or time lapse.
The later is great fun to do, if you get several people to help.
I know of one current photographer that has two assistants who hold onto two highlight strobes, so he has at least five strobes avaiable for a picture. Just looks rather silly diving.

Hi Puffer Fish - Originally 25 years ago I had a locally made strobe by Sea Tite housings and the output on that thing was tremendous. Never had another strobe as strong or as wide and I miss it.
I disagree with you only on one point and that is doing wide angle photography or landscapes (waterscapes), I find I can never get enough light particularly in caves and have to accept 'light up the foreground and accept natural light beyond there. Have seen well lit wa shots and often wonder if they use multiple slave flashes.
Another point for OP is the SnS 110a costs the same as a D2000 and has a guide number of 22 v 20 for the D2000. Didn't check the coverage but I am guessing similar.
