Best thing is type in interchangeable needles in the KH search box. There are already a ton of threads.
You'll find some interchangeables have a much better cable than others. The sample set is a good idea.
Knitpicks - i have a couple sets of nickel plated Options that I love. Have also used the wood Harmony and those are nice, too. Affordable.
Addi Turbo- I have several pairs of these and like them a lot. Expensive.
Denise- nice set, but I personally don't care for plastic and don't like the cable. Lots of people love them though. Affordable.
Hiya Hiya - haven't used them, but have friends who live them. Don't know the price point.
