Ike, I had a look at this but I'm happy with the PT-018 housing that Olympus make. The Ikelite DS-50 strobe looks like it might be a good fit but it seems like the sync cord is hard wired into the Ikelite housing and would not work with the PT-018.
You can be comfortable with any of the housings Olympus makes. DS-50 with Manual Controller shown on following URL is a very capable combination with the #9523.01 tray and handle assy:

Ike, thanks again. I'd prefer full TTL control of the flash rather than manual. Is this possible with the DS-50? The rest of it (arm etc) looks perfect.
