OK, let's remain civil. For one it's only a camera. For two every one is entitled to an opinion.
That said, this is a common question and there are those that love them and those that hate them. And then there are those like me who really think that the SeaLife's, despite offering a strobe etc for a total sum of money less than anything else, aren't worth it in the end
Personally, from seeing so many cameras come through every week, I see much better results from something like the Canon A or S series, the Fujis and the Olympus offerings than with the SeaLifes. I have yet to see any SeaLife shots that make me go OOooo! I wish I had taken that. Plenty of nice shots, to be sure, but just none at that next level. YMMV
It all depends on what you want. Those who have them seem to love them and seem to be very happy with their choices. That speaks volumes to me. You can always start with that and move on if you feel you need to. Just because you buy something doesn't mean you are stuck with it forever - that's what ebay is for
I'd say look at the galleries, but they are still down. Have a search for Jamdiver who dives with a Canon A620 and no external strobe. Seems to me Ed_Dman shoots with a compact, too, though he may have an external strobe. But have a stroll through the photo board - if you are seeing shots you like from the compacts on your list, then that would be a good indication that you're getting what you need. Ask those who have the camera to show you their results. Seeing is believing.
Here are some recent links on this camera/set up FYI I hope it helps.

A search here will find a ton more, but I think they become rather repetitive!
Happy shopping
