DNR Garmin extension
I often use a Garmin handheld for data collection. When I want to pull the data into ArcGIS I use the DNR Garmin Extension program. It works quite well with ArcMap 8.x and 9.x. It will write shapefiles directly if you have ArcMap running but it can also run standalone and write text files if you don't.
DNR Garmin Extension and other potentially useful tools are available from http://www.dnr.state.mn.us/mis/gis/tools/arcview/extensions.html
