I use almost all Sea & Sea gear....strobes, DSLR housing fo D300, DX-1G (Point & shoot) with Sea & Sea YS-110 strobe.
Their gear is top notch. The cameras they use for their point and shoot is essentially a Ricoh GX100. This camera has won numerous awards and is very very easy to use, the best wide angle, full manual options and RAW (like the Canon G9- but MUCH more compact). A good way to pave the way to DSLR use.
Your question is a little vague and depends on what you are looking for. If you want the most in manual options and RAW for the most control over your pictures, there are only two choices.....the Canon G9 or the Sea & Sea DX-1G. I chose the Sea & Sea because the camera itself is also SO much easier to pocket topside being only just over half the size of the G9. THe WA was a huge help too.
