I wanted a set of RS80's when upgrading but couldn't find any in the range I was willing to spend so I went with Kyrsium Elites and they have been bulletproof ever since. My LBS made me a great deal so it might be worth asking for a discount if that's where you got your bike from.
I thought
that too. I got my Ksyriums for $600./flat installed.
I gladly sprung for the MP3 2 Year Extended Warranty for another $50.
