As a professional photographer, or semi-pro, I can tell you that if you start playing the this is better than that, but than this is even better game, it's hard. Digital has made it more so.
So here R some prices.
D70 - This is a BOTTOM of the line SLR, BUT, it is awesome, and this is most UW photographers DREAM setup. Plan on spending 3K or more when it's said and done depending upon your flash solution.
High end PnS - The 8080 is a NICE camera. It does NOT have the SLR speed, but the optics are MUCH better than the 5050/5060 or even likely the 7070. Why, it's pro level SLR glass, and MUCH bigger. So what do you pay, and what does it get you? Well IMO if you have the bucks go with the 8080. However underwater, you are hardly taking photo's of buildings so WA distortion is really not much of an issue.
Keep in mind that the 5050 is a good shooting camera, so this slippery slope does not guarentee GREAT images. Also keep in mind that equipment, while very important in photography does NOT make one a good photographer.
Also a good strobe or strobes can make a HUGE difference in ANY photography that is NOT done in natrual light. One thing that the DSLR solution does that many may not be aware of is the ability to shoot VERY fast lenses, with higher ISO's. And there is the crux of the bisquet, GREAT high ISO shooting combined with fast focus and fast lenses make a difference in UW shooting. BUT it comes at a price.
I promised prices, so from what I've seen the 8080 will run you 1K without strobes, the 5060 will run you $700 without stobes. These are prices including the Olympus housing. If you want Ikelite, then add several hunderd. The D70 is about $1200 with a good, but low Nikon glass. I have lenses that run $2K, and for UW photopgraphy, one could spend a LOT of glass. For example, the 17-35mm AFS 2.8 runs over $1500., so with DSLR glass you can spend a fortune.

Thanks for the help guys, few more things.
Some mentioned the 7070 and 8080. In the SLR world, someone mentioned the D70. I'm looking to "buy once" so I'm willing to up the max price if I know I'm going to get the right setup.
I also heard the wide angle cameras like the 5060 have distortion because they are WA. Is the 7070 and 8080 WA also?
Can anyone explain ports and lenses per different housings? What determines dry vs. wet swapping of lenses?
