a bit late, but.......
i now have a suunto x10 - great bit of kit, but maybe out of your budget? but before that i had the perfect solution (for me anyway!) in the garmin geko - it has a configurable screen to select the parameters that you want to display (speed, height, heading etc) AND it starts automatically when you start moving! how good is that if you have failed launches and forget to reset, lol
to top it off you can download straight onto google earth (or is that my x10 which definitely can) so that you can see your track - which by the way is good to keep incase you are reported for being somewhere that you shouldnt (ie built up area)
