Boxed or no Box

This is a great board to read about the Thundercats. However, is everyone here only collecting the boxed items? I asked a few question to some that were selling, and they are all boxed.

Also, I have the same exact Cheetara sealed in the box as the one on ebay that $1,200. It is totally exact, and I can not figure why it is $1,200 and there are some that are $150 range. Is it all to do with the grading that was done on it?

Here is my photo:
