Looks to me like that model is still being sold. Furthermore, it seems that they do market a lifetime warranty for their products.

I was going to shell out some coin for rollers, but now I am not sure I'd want to do that considering that Kreitlers are more expensive _and_ they clearly do not honor their lifetime warranty (if what you say is true).
