New chain and sprockets

[Cutty72]

Ok guys, it's time to replace the chain and sprocket's on my fianece's SV.
She uses it mostly for commuting, so I don't necessarily need the Joe cool racer boy stuff, just something that's gonna last. It's still on the factory stuff at 16k, so I'd like to get at least 10k out of the next set.
What's your recomendations?

SBTG recomends Pit Bull sprockets and the D.I.D. ERVIII chain. $200 to my door. I've never heard of the Pit Bull sprockets, so I know nothing about them.

I also found a few others.
