I just ordered a 9sp chain for $9.16, shipped, from Nashbar:
http://www.nashbar.com/results.cfm?category=76&subcategory=1099&storetype=&init=y&pagename=
It's product #NS-CN9. Free shipping today until midnight, code SHP510.
When you click to the individual product page and shopping cart, it lists
the price as $14.99, but I called and got the $8.45 price.
I've been using this same model chain for about a year. It's been as good
as any other. Some older KMC chains were absolute [censored], but these days
they're great.
The 8sp one on my MTB has been great too. In fact it's half of a tandem
chain that I bought for under $10.
Stock up while you can, it's worth it -- unless the tandem ones come on
sale again!
