Everything has a tendency (however small) to fail. If you're asking "will I have to replace this in a year" the answer is probably not. . .depending on how hard you ride it." Get the flash; longevity shouldn't be a concern when purchasing photo equipment for hobbyist users.
Remember the days of the flash cubes when each of the 4 sides would just blow the hell out of itself when it fired.... Those were funny, but not quite as funny as holding up a pile of black powder and igniting it for flash....
Sams/Costco will take it back no questions asked if it fails. Being a noob I had no idea how long they last.
Thanks everyone!
Also, nobody locally would come close to matching the price. One guy said "Why dont you buy it at costco?" to which I replied "You know what? I think I will"
