Hi guys and girls. I am getting into commercial diving in 12 months and would like a semi professional video and still camera around the 1-$2000 each mark. Any ideas? As far as the video camera goes am I better off with a hard drive camera, a memory stick one, a tape one, a new high def one? I want good photos and video footage but without the $5000 pricetag.
Thanks in advance to anyone who helps.

Don't know about video, I'll leave that to someone else.
If you mean camera only, have a look at the Nikon D300 and the Canon 40D, they are the newest 'prosumer' cameras which both are excellent for most UW work. They are in the 1200-1700 USD range. But you will have to add UW-housing, lenses, ports, strobes, cables... And the total for a complete rig will be more than 5000 USD.
If you want a complete rig for maxiumum 2000 USD, better look at a used Canon 20D or Nikon D100/D70s with an Ikelite housing. Even if there has been a lot of development, those cameras still can capture some awesome images. However, it might be tough finding something complete for under 2000, even if you look at models that are 3-4 years old. You will probably be able to pick up the camera body with an UW-housing and perhaps a port, but you still need to buy some lenses and strobes, as most of the guys and gals parting with their system are upgrading to the models I mentioned initially and can use some of their 'old' stuff with the new.
good luck
