Query: Canon cameras are terrible!!!!!

I bought my Canon camera thinking it would be a good quality camera. It worked fine up until I owned it for just under 15 months. The screen went black, and like so many others with the exact same problem, Canon REFUSES to fix it. Saying it is out of warranty. Bottom line is that Canon produced a line of defective cameras, and I for one will NEVER buy another product that bears the Canon name. Now, all I have is a really expensive paperweight!!! I hate to throw it away! Maybe someday, Canon will come to its senses and offer to fix it. But I won't hold my breath. If you are even remotely considering buying a Canon camera, I would strongly recommend not doing so. Their customer service is absolutely among the worst I have ever seen and experienced!
