any difference in the bezel/rear housing between different Note 2 models?

[maximus96]

I have a small chip on the front bezel of my AT&T Note 2. It looks like I have to replace the whole rear housing in order to replace the bezel. I see different models on ebay ranging from a few $$ to $20+. The AT&T version seem to be among the most expensive...Does anybody know if there are any differences between the different models?

thanks
