[Diy_efi] Fast updating (20Hz) GPS receivers for track

Well, if you lived in Germany it would be like 15 Euro's out the door. However with shipping to the US that becomes 70+ Euro's. But still far cheaper than the original poster's 1000$+ for a 10 Hz GPS :-)

I bought one anyway as I want to check it out with my navigation/rally software which needs more than 1 Hz updates.

The URL for the place in Germany is: http://shop.trenz-electronic.de/catalog/product_info.php?cPath=105_139&products_id=744
