The only standalone Dataloggers I know cost >$200,-.
That was the reason I was that overwhelmed when looking at the NaviGPS. (Do I 
repeat myself? No I would know ;-)

The NaviGPS logs plain NMEA and you can specify which Dataset you want to be 
logged on the SD Card. 
Assuming a 2GB SD-Card and a NMEA Dataset between 80..500Bytes. This summs up 
to 7MB/day .. 42MB/day on 1 second recordings
So that's at least 
     48 days with 24h/day with __EVERY_ NMEA sentence logged.
    300 days with 24h/day with 1 NMEA sentence/sec logged.
Hear the salesman speaking ;-)
 Does that sound like a device to log tracks for OSM. 
 And it's "only" arround $113,- for the Bluetooth Version

That's the reason I ordered some for testing on Friday(yesterday). I'll write 
more on the list as soon as I really got hold of them. Which is hopefully by 
the end of next week.
