Mogui, the link I provided was for Jakks Pacific who makes many of the officially licensed all-in-one games you can buy at the stores.
The Nintendo Clone has appeared in a number of varieties and quality levels. I've seen several and own a couple. Every one of them appears to be less than top quality construction. They are definitely a clone of the Famicon system in Japan which was widely cloned by China back in the 80s'. The inclusion of all the games and somewhat questionable manufacturing screams bootleg, but I've seen these units on sale all over the country at mall booths, flea markets, and reputable web sites. Just never seen one at a major retailer. The web link below is to one of them. Just make sure if you order, that the seller has contact information available on their site and is not one of those anonymous web vendors. That's my first test of legitimacy.
