Replying to Sony ECM-CG50 vs Rode Videomic +KK!

I've been looking to improve the sound in my video on my T3i, as audio is 50% of your video. I am now tied between these two the Sony ECM-CG50 and the Rode Video Mic. I have ruled out the VideoMic Pro because of terrible reviews and poor construction for its price. If any one has experience with the Sony mic PLEASE let me know. It looks to me like its built a little nicer then the Rode, but im not sure sound wise because there aren't many reviews online. Thanks NS!
