https://www.simplymaya.com/movie_page...html?cat_id=23 those are the free simply maya videos, they'll work for any version of maya you are using And to my knowledge maya ple is free there isn't a ple available for sale, if you buy it, it will not have the watermark that the ple version has and I'm sure there will be a few other things you get with the one you buy but I'm not sure, never used the ple version. Hope that was helpful.
