Full HTML in Flash / Flex

I was wondering what are the components to display full-fledged (or almost full-fledged) HTML in Flash / Flex. In particular, you need to download external CSS files, custom styles, and so on (by the way, js is not needed). And that's what I managed to find:

• IFrame - where the iframe is overlaid on top of the flash drive with js. Somewhere I stumbled upon an article that is not worth doing so for <list of reasons> .
• HTMLWrapper - I ’m picking it up now ... It seems there are a lot of pitfalls. But this is not a browser, which is in the player, which is in the browser ... It’s all the parsit itself, all the dossier itself and it’s all drawn ...
• A paid component HTML Component for Adobe Flex - but I would still like something open-sorsno-free ..

It looks like HTMLWrapper is the best option.
