Broken Shutter button - Again!

Well, the shutter button on my 30D has yet again bombed out. What happens is the button is pressed and nothing happens, then varyingly in seconds, the shutter will then operate. If I switch the exposure lock and focus to another button so the shutter button only operates, the problem persists. It's a bad problem because the photograph is not taken when expected. Needless to say I am frustrated with this issue. So the camera will be gone for 2 weeks and I have to eat the cost of shipping, bummer. A part such as this should be built to more durable standards. I take a lot of pictures everyday and need a tool that is dependable. Maybe the 30D was built more as a backup?
