Yes, I agree with you, strange market alignment for the 10D.
Also the optical flash triggering with the Inon X-2 housing is not my preferred method.
I have called Bruder yesterday (http://www.bruder-uw-technik.com). They build pretty solid carbon housings for a very attractive price. The housings are very light and need a weight for becoming neutral underwater. But very nice for travelling (weight in the cargo compartment). The housing with full controls costs 1300 Euros. He would even skip some controls (I really don't need to set the clock or erase pictures underwater, don't care about WB -> RAW) and it will be even less. He also builds the dome on customers request for nice price. The fisheye dome costs around 500 Euros and has 250mm diameter hemisphere (acrylic, but glass is also available). Built time upon order is about 3-4 weeks for all of it.
For the time being it's my favorite. But this can change quickly :oops:
If choosing a housing without E-TTL-Conversion (almost any right now) it may be of interest to you: http://www.muenster.de/~matthias/blitz/indexe.htm
I hope the circuit will be available in July. I really like the idea because it would be independent and possible to build into almost every housing.
From the past Matthias Heinichs promises worked out great. The prototype works already he said. So I really hope this one will work great.
