[Wolves] GPS Data Logger

[Rob Broadfield]

Can anyone recommend a decent GPS Data Logger that I can use whilst
cycling (mountable on handlebars) that is compatible with Linux and that
will upload routes to Google Earth and/or Open Street Map?  Preferably
one with a display (with backlight) and will record:

Waypoints (at the press of a button)
Time
Speed
Distance Travelled
Altitude

Other useful features (not essential):

Calories burnt (after input of body & load weight)
Ability to preload routes

Any suggestions based on experience of using one of these devices would
be great.

Thanks
