Good deal? Yes/no?

I'm thinking of jumping on this deal to get an s3. I was thinking s4 but since I typically root and put a rom on it I figured it wouldn't make much of a difference. I was just wondering if y'all thought this was a good deal still. Also, I'd more then likely throw cynagone (sp) on it does the s3 have a solid version of it out? Sorry for errors I'm on my iPhone 4.

oh one more thing- is there a texting app yet for android that pops up and you can reply from anywhere?i wish Iphone had one.. I kinda recall hand cent doing this but I'm not sure i could be mistaken.
