60csx / etrex hcx -> Log to data card = huge capacity datalogger
You can set the 60csx to log directly to the data card. The etrex hcx models also do this. (it will still log to the smaller internal memory and can be set to 'wrap' which keeps the most recent track points in case you need to track back).
Look at page 26/27 of your user guide. ( http://www8.garmin.com/manuals/GPSMA...nersManual.pdf).
Or go to menu>tracks>setup>data card setup>
tick 'log track to data card'
I've set my etrex hcx up to record a track point every second.
I have a 2GB micro SD card with maps loaded for Western Aus, I went a bit over the top with maps from 4 sources (shonky maps, tracks4aus, OZtopo + Garmin City Navigator), these take up 121.6MB, leaving 1.7GB free.
This gives enough track storage for 270 days if I use the GPS 16 hours per day.
If you have more maps, or are going for a longer trip you can always buy more microSD cards (mine was only £2.55 delivered). The tracks on the microSD card are in GPX format and cannot be read by the GPS receiver.
