Love the Canon stuff. Still have my G10 and S80. Even though I've just bought the Oly OM-D, the G10 is still in the bag.
There's a replacement screen for your elph on eBay for about $24. A precision screwdriver and some good light and you can replace it yourself. The seller provides instructions and support. It's just removing a bunch of little screws and a ribbon cable. Then assemble in reverse. I did the screen in the s80 after the wife dropped it. I figured I didn't have much to lose and everything to gain. Still going four years later and still an awesome camera.
