I heard back from Knitter's Pride customer service. Basically, the set sold on Amazon that was on par with the Harmony needles price-wise is not considered to be from an "authorized dealer"and therefore I'd be out of luck if a needle broke. My alternative is to buy it from an "authorized dealer" and pay $20 more for a set. I was a little confused because I saw a couple of Amazon reviews that mentioned they got replacement parts. I want to get something that will last, but also something affordable, so I am trying to make sure I'd be covered. I don't want to rush out and buy anything just yet, but I am excited to start knitting with a new set of needles! Pretty, shiny needles that will improve my knitting experience from now on.
