I'm unsure if someone else recommended this remote or not. But certainly i did. And google also might also if you gave it a try. Also, someone above my post also recommended a $9.99 solution to your problem.
As for not wanting the camera to offer 30+ second exposures....you are putting words in my mouth. I never said such a thing.
In fact about half of what i shoot is 30+ seconds considering i'm the father of two young children and pretty well can't shoot until they go to bed at night. Funny as i have no issues in doing so with a $9 remote. And yes, it's very reliable. And if it weren't at that price you can probably afford three, just in case.
You don't need the camera to wipe your a$$ my friend!
