I've owned a wide range of flash drives, because I tend to lose them, and I've found that corsair just can't be beat.
I haven't used the flash voyager one that Gerbil posted, but it looks like a superb deal. I might invest in it myself.
Patriot is okay sometimes, but I find that the terminals connecting the male usb pull off after you use it for a while. May have just been my luck though. (experienced with 2 patriot flash drives.)
