Not to derail thread, but one other item that I think really COMPLEMENTS (but not replace) a mirror is the Garmin Varia radar. It alerts you to vehicles behind you and even gives you a graphic representation of number of cars and proximity to your computer head unit. I am a notorious cheapskate and the $150-200 price tag is worth it IMO.
NOTE: This advice applies to roads with occasional cars. For city riding with constant cars passing, skip it and stick with mirror and ears.
