The DS-125 is a great strobe, I use two on my DSLR, but it may be a little over-kill for what you need. What housings do have, or plan on using? The Cannon housings dont come with a tray so you would have to add that. The cost of the DS-125 and tray is way more than your camera and housing. Plus the size of the Ike tray, and DS 125, is huge compared with your compact cameras. You might want to take a look at the DS 50 setup, its smaller, lighter, and about half the price of the DS 125. My wife uses the DS 50 with her Nikon 995 and it works great.
