+1 Actually, +lots. I had all kinds of issues with SD card corruption, and HDMI flickering, even tried a couple of different USB power supplies. Eventually bought the damn officially recommended one from element14, and then everything was fine after that. My take on this is that the raspberry pi has cheaped out considerably on power filtering capacitors as it seems even the slightest ripple or voltage fluctuation causes bad effects on it, when other devices (cubieboard, radxa rock, beaglebone) will run fine on the same source. >> I have read stories of people spending lots of money on SD cards and >> finding none of them work, so am a bit nervous about doing this myself. > > People buying lots of SD cards and none of them working?

Oh, one other thing -- I found that overclocking the raspberry pi caused me sd card corruption too, so if you're hitting issues, try going back to stock speeds.
