After learning how to import the tcx file and use the cue sheet on the Garmin 500, ridewithgps has become my favorite. It also does a good job with mapping and cue sheets. If I'm in unknown territory, I usually print a hard copy of the cue sheet and a map, and sometimes make a few extra copies for friends that might need them. There's several others that do almost as well (mapmyride, garmin connect) at mapping and cue sheets, but no customized printing.

I know you can use photoshop or another drawing tool to label street turns on the map, but was hoping that there was a mapping tool that would have this built in. I prefer using a map since it is easier to follow, but a cue sheet is a nice backup.
