7-Segment LEDs

I'm looking to add 6 7-segment LEDs to my project using a MAX7221CNG+ chip. The instructions located at Arduino Playground - MAX72XXHardware, say there is no way to make a common anode-type matrix work with the MAX72xx and they only give examples for common cathode 7-segment LEDs. However, it seems that most 7-segment LEDs are common anode. I can only find a few common cathode ones and they are rather expensive.

Could anyone who has 7-segment LEDs working with a MAX72xx please recommend a place to get the LEDs?

B.G. Micro (www.bgmicro.com) has some. Looks like they're all older ones, though, so they'll be fairly dim by today's standards.

You might also look into some of the chips that can work with CA displays, like the ICM7218 and SAA1064.
