both but mmc seems to be slightly cheaper

thanks

Furthermore by now SD is faster than MMC.

I have been trying to find out *how much* faster. Sandisk's web site tells
you how fast their Ultra II devices are, but I couldn't find anywhere where
they tell you how slow the MMC devices are!

Don't know where you get MMC cheaper. I really don't know the
difference, but the MMC cards are MUCH more expensive around my part of
the world.

MMC are all guaranteed to work at 2MB/s; I'm not sure if they come in
higher speed grades or not.

The smaller SD cards run at 10MB/s, the larger cards (around 512MB or
more) run 20MB/s. As it's a synchronous interface (eg, clocked
entirely by your camera, not the card), your camera is primarily
responsible for the effective speed (unlike Compact Flash, for
example, which is an asynchronously clocked interface, the speed being
based on a handshake protocol between the card and your camera).
