Another KMC chain user. I have had pretty good luck with them, and run them on most of my bikes.

Its always good to have a chain tool if you own more than one or two bikes. I like the park CT-5. Its small enough that I take it on tour with me, but robust enough to use in the shop. The CT-3 is bigger and more expensive but nice.
I also have one of these, https://www.amazon.com/Bicycle-Break...+chain+breaker
not to bad.

In a pinch, you can just get one at walmart, but it will be pot metal and break pretty fast. Might last long enough though.
