I'm looking to buy a housing for the D700. Can anyone explain why there is such a big price difference between Ikelite (~$1500) and any of the others (+$3000)? Do the others have a performance advantage? Can't see why I would spend almost twice the price over Ikelite.
I'd appreciate if anyone has an explaination and or advice.

As Larry said the Ikelite are polycarbonate plastic compared to metal housings like Aquatica, Nauticam, Seacam etc etc.
Basically the difference in price is due to the different way the metal housings are produced. Machined from solid Aluminium costs alot more than cast ploycarbonate.
There are a few adavantages with metal housings compared to Ikelite. Mental housings are generally stronger build. This is shown by the deeper depth rating of metal housings. Some are rated passed 120m. You might not need a housing rated to 120m but it shows that the metal housing have a strong build quality.
Having a machined finished housing also means that the buttons and controls are more precise which allows for a better feel of your cameras controls.
Metal housings also allows for more options with other components like strobes. You can order housings with different bulkheads for different strobes compared with Ikelite your limited to just their strobe bulkhead.
Another important item is aditional Viewfinders made by Inon, Nauticam, Aquatica. These basically improve what you can actually see through the housing and give a more detail sight into what your shooting. These viewfinders are expensive but once you have used one you can actually see the big picture so to speak ;-). These viewfinders are not an option with Ikelite.
Another option when looking at housings is also the quality of the matching ports and domes. The metal housing companys also make their ports and domes out of metal compared to ikelite plastic ports and domes. Again these domes and ports are more expensive but are made to a higher quality compared to Ikelites polycarbonate ports and domes.
Best way to get an idea for yourself is to go and have a look at an Ikelite housing and compare it against one of the metal housings like Aquatica, Nauticam and see for yourself the difference in build quality and finish.
But seriously if I had a an excellent camera like the Nikon D700 I would not consider Ikelite as an option for housings. Like everything these days you get what you pay for.
