Your problem is just bad luck. Compact flash is highly reliable and has been used successfully by hundreds of thousands of consumers.
Maybe your issue is more with SimpleTech than compact flash. I got a bad SimpleTech compact flash once. It turns out the internals were loose. When I lightly tapped it I could hear the chip rattling around. That's bad manufacturing quality control, not a fundamental shortcoming of compact flash. Try Kingston instead.
Two of the main differences between compact flash and secure digital are that compact flash is larger and heavier and secure digital is more expensive (e.g. ~$45 for 256 MByte CF vs. ~$80 for 256 MByte SD). Secure digital also has features for controlling copyrighted material, but that is not relevant to kaga's intended use in a digital camera.
Here are some current deals on secure digital memory:
