What's a good list of browsers to test your web design with?

I'm trying to come up with a list of essential web browsers one should test their design on.

Here's what I usually use, but I would love to know if you would recommend others that I have missed?

• Firefox
• Safari
• Opera
• Google Chrome
• Internet Explorer 6 - 9
• Camino
• SeaMonkey

I know there are plenty more out there, so tell me what you use!

In my opinion you're already testing far over the top - IE, Firefox, Chrome & Safari already corner more than 99% of the market in PC / Mac form. However, you could also consider testing against mobile devices on Android and Safari on iPhone.
