Micro SD card (SPI) to USB converter

Hello everybody,
I made a GPS data logger which logs information like ,Longitude,Time & Date etc,. into a 4Gb Micro SD card.
Now, every time I have to pullout the Sd card from my device and insert into my computer and have access to the files logged in, I want to go a step further, I want to add a SPI to USB converter. Where I can directly plug in my device and have access to those files.
I made a little research on the internet and found this converter

Please suggest me.

P.S : The converter should be bypass type where it should allow logging data while logging and and give access to SD files if only I connected my device to my computer.

Thank you
