USB Drives — Recovery?

pipingguy writes "Now that 'thumb drives' are so inexpensive (a 1-GB SD card with USB housing/adapter costs about $25), which programs does Slashdot recommend for system recovery? What is the need-to-have software? Additionally, I'd like to get some input on the durability of the newish card reader / adapter devices, as some of them seem to be pretty flimsy (but very useful/flexible as opposed to the old fixed-capacity NAND devices)."
