GPSNOW has the GPSMap60CSX for $399, Topo map software for $89. A 2gb micro SD card can be had from several sources for just over $20.
I bought my 76Cx from GPSNOW from them for $349.
I have seen the whole package 60csx, topo 08 and 2g card for 399- deals are out there and will only get better the closer it gets to xmass!
happy hunting.....
