I just solved it with more regulator sets....

Found this one: http://deal.bts-eu.com/hank_neu/BILDER BTS EUROPA AG/BC - before Christoph/2008 - 2009/BtS catalogue JPEG 300 dpi/34 Adapters/BtS 16910611 twin outlet converter 300 bars.jpg
But the website looks as if it is not being maintained.
For inquiring minds, I am looking for a solution where I do not have to be constantly reconfiguring my regulators if I want to or need to switch between doubles and singles on a trip. I was doing some shore diving in Bonaire with doubles, but they wouldn't let me take them on a boat trip. Having to reconfigure the regulators and back is a lot less time effective than just screwing in an single to dual adapter with or without isolator valves.
Thanks everyone.
You're welcomeOrdered the one from sub gear/scubapro on eBay yesterday. Not sure if is can be used underwater, but worth a try.
The sockets are sideways so maybe there won't be any head banging issues. It has no isolator valve, but it's just so I can use my doubles regsets for an occasional rec dive anyway.
Thanks again everyone.
One surprise before I left was that the center port on the manifold would not seal properly with a standard 200/300 din to yoke adapter. I ended up having to grind off a few threads off of the adapter. This was due to the fact that the din manifold was the 232 version and the din nipple was not long enough to seal on the standard 200/300 bar din to yoke adapter.
So if you have a choice between the 232 and 300 bar versions, get the 300 bar manifold version so you will not need to grind on your adapter.
