Hesitating between Tralog V2 shield and Cooking Hacks 3G/GPS Shield

Hello everybody, this is my first post in this forum . I am new to the arduino world and I plan to build a GPS car tracker. After googling the needed components, I came out with two All-in-one tracking shield for Arduino Uno.

1- The Tralog V2 from RocketStream http://www.rocketscream.com/blog/product/tralog-v2/ 2- The 3G/GPRS + GPS shield from cooking-hacks http://www.cooking-hacks.com/3g-gprs-shield-for-arduino-3g-gps

What I want to do by far is logging the car GPS location into the Micro SD Card and send it by 3G network to a remote server.

My questuion is, which one do you advice me ?

thank you.

Choose either one. They’ll probably both do the same job for you.
