Bought the Mountain Mirrycle Mirror (no, I did not spell it wrong, that's the way the company spells it) at Amazon.com for $13.95. Mounts on the end of the handlebars. Was easy to install, took about five minutes. This is a really fine mirror, it is convexed just the right amount to give you a great view of what's coming up on you from behind. I was not disappointed for a change, this is a quality product.
