[OSM-newbies] buying a gps

[qwerty at qwerty.is-a-geek.org]

Hello All!

I want to buy a GPS reciever that can both give me guidance when driving 
my car and also save tracklogs that I can use for osm.
I read this part of the wiki gps-review section:
http://wiki.openstreetmap.org/index.php/GPS_Reviews#MobileNavigator_4.X.2F5.X

And in a nearby store they had a sale on a Navigon TS7000T and I wonder if 
any of you know if that one also has logging feature?
And if these Navigon units can cape to log every second, since I read 
about problems with tomtom units on the wiki gps review page about logging 
every second?

Thanks in advance for all help :)

Best Regards Patrik Andersson - Sweden.
