Hi
I use a sony P9, which I think should be substantially similar to the P10. I use a Sea & sea YS 25-DX strobe, and it works well. I guess the more powerful YS 90 would work better, but I'm only guessing on this.
To sync the strobe I have a fibre-optic link that attaches onto the outside of the housing and covers the internal flash. Sea & Sea sell these they give you a template to customise the fibre-optic attachment to your housing (eg Sony/Canon etc). It is done with velcrowhich sounds a bit naff, but works fine.
The P9 DOES pre-flash (so I assume the P10 does too), this means you have to get a strobe that will ignore the pre-flash and fire on the main flash. The Sea and Sea strobes do this (the ones designed for digital use).
The casing for the camera covers the focus illuminator so focussing in the dark is a problem (as ReyeR states).
The external strobe makes a world of difference to the quality of pictures you get from the camera. The only exceptions are really close up in clear water when the internal strobe is OK.
