I'm not sure on that one. My two clones are hard plastic not the aluminum cased ones. I prefer these as the aluminum ones seem like they would scratch easier. I could be wrong about that, but that is what it seems like to me.

Based on the different casings, I would say there are a few different manufacturers out there.

The menus are the same on both of mine. Nothing fancy but they get the job done. Not sure if the menus are the same on clones, but I would guess they are pretty similar.

Video quality is very good for the price. I've downloaded movies onto mine and have no trouble watching them. If you are planning on watching movies on it, I would recommend downloading Virtual Dub from this website. It really helps the video quality.

Wish I could be more help, but I don't know much other than what I've picked up here and from personal experience with mine.
