They do have a lifetime warranty. Avg is around $250 shipped. Right now I would suggest saving for the Illuminas. I have seen them for $65 each and another for $280 shipped. The Illuminas will probably be worth saving for just for the added ability to change the stiffness. I do not know any links off hand but check out ImportHookUp and find a special on there.
