I ordered mine on Amazon, through the Ace Hardware Outlet store. Yep, $15 and you get enough for 2 lenghts. I also used chain saw bar oil to lube mine
I also got this chain breaker which so far, works very well
Amazon.com: Farmex/Speeco #25-#60 Roller Chain Breaker 05050: Automotive
Also, I ordered a pack of 4 master links. So I'm good to go! And yep,, I'd say 100% improvement over the kit/bicycle chain.
