I will shop around and probably get a 2GB CF card to go with the 1GB xD card I ordered. I have heard a couple of horror stories about no-name brands failing shortly after use so will stick with the more reputable ones. Though you all have said you never hear of cards failing (and I agree with you there), they do have a limited lifespan...though probably a longer one than that of your camera. Here is the relevant info from the article Gradient linked to: "Individual flash memory cells have a limited lifespan. That's the bad news. The good news is that their lifespan is usually measured in the hundreds of thousands or even millions of erase/write cycles, and that the better controller designs utilize an algorithm that's designed to balance the wear across the entire card's cells. CompactFlash and SD cards are designed to automatically and transparently map out memory cells that go bad, or in some cases when they reach a predefined limit, i.e. 300,000 erase/write cycles (note that this figure is just an example; manufacturers may use a different figure). Cards should continue to function long after a few cells have expired, since even the busiest photographer's flash memory card won't start turning off a significant number of memory cells until after many years of service."
