d.a.v.e

I've got lots of Nikon gear so I am not really open to the other folks out there.

I am new to underwater photography and just want to mees around with it when I go to HI next month.  I'm looking for a basic set up d70, light, housing, maybe a lens?  Would love a housing for my D1x/h or d2x/h but am guessing those are out of my price range.

Let me know if your interested in selling...

I've got a fair range of nikon glass and am thinking of picking up a d70 for underwater & vacation use.  What lens is a good all around lens under water?

Here is my story... I am a full time photographer (land).  I've been to HI and a few islands several times now and have been frustraited not being able to really take any underwater pictures.  We have decided to go back this year and I really want to spend a few days messing around with this.  I don't see this as something I will use more then once or twice a year.  So far my only experence (with a dslr camera underwater) has been with the underwater bag things & a swimming pool & a light up top, this gets me some neat shots that sell well at swim meets.

Anyway I would not mind setting aside a budget of around $1500 to try this endevor.  I shoot nikon so I have lots of Nikon lenes & dslr bodys (d1x/h & d2x/h).  Ideally I would not like to have to buy any new lens/body combo.  I would perfer to put my money towards lights and a housing unit.  What should I be looking for?  Can I come up with anything for this budget (I don't mind buying used)?
