Was about $87 when I got it. My current camera tops out writing at 1.3MB/s so it would perform about the same as the $55 cards @ different online retailers...
I use a couple of hitachi 4gb type II, and 1 ea of sandisk ultra II in 1gb and 256mb. I generally leave the 1gb sandisk in for everyday shooting, and pop in the 4gb when I am away from home and know I will be shooting lots of pics. There is a rather large difference in record time between the two - so shooting in continuous drive works better with the ultras.
