Brookstone had 'em
Nice wide-angle view, clips right on, I can see out the little back windows and even the right side of my face smiling back at me. Sounds extreme, but it's not like those weird half-globe things you see in stores afraid of shoplifters and hospital corridor corners. It's actually easy to get used to and I can't drive without it.
I couldn't find it on the brookstone.com website, though... I googled the thing and found this for you, looks identical to what I have right down to the price:

You might check your mall Brookstone store, I can't imagine they discontinued the mirror, but stranger things have happened... :wink:
