Is the Extreme (133) worth the extra over the Ultra (60)

There's a performance database below:

But I'm sure while reading that someone will reply with a real-world answer

Depends on the camera, for an EOS 350D/D70 probably not, for an EOS1D series or D2h/D2x then yes it probably is worth it.....

Should have said, for a 20D

Well if you look at the figures in RG's database the Ultra II is some 0.0x something slower than an extreme III in a 20D, so I doubt you'd notice the difference in camera. IF you have a decent card reader, you might notice the difference in downloading to your PC, but many card readers have shocking performance.

Personally I'd go with the Ultra II, and either save some money or get a larger card. I use 1GB cards and sometimes really wish I had a 2GB...
