I have an ikelite 100a substrobe in excellent shape. Includes arm, sync cord(nikonos 5 pin) and substrobe. With the substrobe you can use with digital cameras in manual mode on camera and with the manual mode on substrobe. No ttl as the digital cameras are dttl. I would like $225usd plus shipping. I have used this strobe with a nikon d90.

Thailand i a good location. Similian island is good. Diving season starts around november to similians. They did get hit by very warm water about 4 years ago. On some sites it did damage coral so the park has closed some sites from diving. I have been on 3 trips there and found lots to photograph. There are boulders the size of houses and at the bottom there are swim thoughs and that is where alot of the soft coral is. To see some photos you can check my website out. The silmilian island part was shot in january 2012 so you can see the variety of colors thailand offers. This was after the warm water which killed some corals in the shallows on some sites. There is current on some sites. There are alot of liveaboard boats which cater from the budget to expensive. The more expensive the boat usually caters to more experienced divers as well as a better setup for diving. There are a few cattleboat liveaboards there.

Yes you could use either strobe as slaves but the ds50 has less power than the ai and if you shoot ttl the camera will turn off the ds50 if enough light for the picture. Your ai strobe will fire on either 1/2 or full power. I think 1/2 power would be close to the exposure. Overexposure of picture is the problem you might have. As far as  which ikelite slave sensor i have not used either so i am unfamiliar with them.

Check out Mermaid liveaboards trips from bali to komodo. No extra flights needed. Mermaid 1 does 9 night trips and Mermaid 2 does 7 night trips. Same route but mermaid 1 has more time to spend in komodo park. I have done 6 trips on mermaid liveaboads and enjoy both boats. Mermaid 1 does have more space and the extra 2 nights is the one i prefer. The trip from bali to komodo has excellent diving.
