Anyone has Leader Class Optimus and 20th Anniversary Dvd Prime?

I already have the 12 inch Dvd Prime and was wondering how big is the Leader Class Prime compared to the 12 inch one. Also whats the current retail price for leader class prime? I saw someone posted a pic and the price tag said $19.99???
or is it $40?!
It would be cool if theres a comparison photo of the two. thanks
