What GSM module for interfacing with Arduino?

Hi everyone! I'm planning a system for remote operation of my cabin. I'm thinking of using a GSM module that will send/receive text messages and perform a given task.

Do you have any modules to reccomend or experience with any of the ones below?

I've found some..

The first is from http://www.hwkitchen.com/products/gsm-playground/, and the second is from http://www.libelium.com/tienda/catalog/product_info.php?cPath=21&products_id=59.

Any experiences?


can't give you any advice on modules but i successfully interfaced a gsm phone using AT commands.

I'm sure I'll get it working with both of theese modules, but I'm looking for something reliable. that won't lock up..

Maybe I'll just get one of them, and learn the hard way..

this is the cheapest/easiest solution i've found: http://www.opengpstracker.org/

Hope that helps!
