I vote for Magical Racing too. Nice wide view from the special glass and the carbon doesn't degrade over time. They're also adjustable in various ways. Really good design.
Probably quite expensive - but you get what you pay for if you go for something cheap.
I run the Lockhart phillips carbon race lite mirrors. They come with either 55mm or 110mm stalks, so you can get in tight or longer. They look great and are a good quality about $115 a set,but well worth it. Chaparral motorsports is where i got mine.
