now that you have upped your pricerange, you have many more options.
for your depth range, 150', I wouldn't recommend an Ikelite housing. I have seen that the push buttons get hard to operate deeper than 100'. It still works and is water tight up to that depth, but it doesn't work as well as you will want.
Equinox has a deeper depth rating, not sure it it has the same issues with buttons being stiff at depths over 100'. It would work in your price range, though.
as far as camcorders go... look at some of the Canon and Sony models. Many very good ones are priced in the range $750-1000. Be sure you get one with a low lux rating, wrecks are dark and you don't want a camcorder that can't focus well in low light.
if you are shooting penetration of the wrecks you are going to need a light of some sort. Lights can be very expensive, may blow your budget. But if you get a good camcorder with low lux rating, you may be able to shoot inside a wreck with illumination from other divers handheld lights. It won't look the same as a dedicated video lamp, but it will be much cheaper and may be what you want anyhow.
Also, I found that in editing, I was able to do some white balancing on dark shots inside a wreck. I liked the results. My video light was actually too bright at times, plus it made the silty interior look terrible. So I did much of my video with it turned off, used the other diver's handheld lights as my source or light coming in from doors, etc. Just my 2 cents.
