So my chain is about two years old, and it's already showing it's age with a decent amount of unreliability. I figure it's about time for a chainge (see what I did there?) and am looking through JensonUSA for some new chains. However, there are too many options (9-speed, Shimano) and I'm hesitant to go the cheap-o route, but at the same time hesitant to spend more than I need.

What's the deal with the pricing points of chains, at least for Shimano? Is there a "best compromise"? Obviously, I don't need Dura-Ace, but even that chain is only $50 or so, which makes me feel like I should buy it simply because it doesn't seem so expensive (though, obviously, it's the fact that it adds up).

Edit: fuuu I typo'ed the title
