Want a great mirror for your upright “city bicycle”?
With a little tweaking, the Sunlite Deluxe will fill the bill. You can order through Amazon or directly from the retailer, Bicycle Source US.
Through Amazon, the mirror was $11.99 with free shipping (Feb 2, 2013) whereas the retailer offers chrome or black at $17.99 (+ $6.95 shipping) (April 8, 2013). 
It was not available per my preference at local bicycle shops with which I checked.
This is s high quality product and installation is straightforward. The 11.5” arm is practical and the 3.5 X 5” mirror face is the biggest I have ever seen.
In my bicycle’s case, I had to bend the arm somewhat to get a better view around my left arm.

Protecting the threads with 2.5” of snugly fitting of 9/16” o.d. Tygon hose, I clamped the threads in a BIG vise and bent the arm with a BIG wrench cushioned by a double fold of heavy cardboard. This is a trail-and-error project, and I may have to do another bending session.
