Looking GPS Unit for Canon 5D Mark II -URGENT HELP REQUIRED
 

Ok here it goes, i am traveling next month and I want to get a GPS unit (a good one not so expensive) to it can add the location of the picture to th e EXIF files on spot after Taking the shot,

i have found some GPS Units but the reviews of them were bad, as one needs to download and one needs internet connection, since i am going to an open areas in UK i won't be enjoying carrying a lot of equipment to it will GEO tag the pictures,,,,



anyone can advice me of one that can do it all without the need of intent connection and works on spot after taking the picture??? :)
