The best compromise I found so far

Recall the feeling of the snes controller on PC or others is not necessarily easy.
USB adapters can certainly use with the original controllers maintained but even they are beginning to age (older came out in 1990!) And it feels.
Either find gold prices and adapter via an official reply that Nintendo had released for the Wii.
Either buy a clone like this one and there are many! Often at low cost which can be tempting but at what price.
To have tested a few. Frankly, it is often very very mauvaiset unfortunately I can not quote you the marks to avoid.
As I began to give me a reason. It happens that I have tried this model and made me realize that it's not at all ... dégeu plastic hull is of lower quality than the original, but frankly it's really better the concurrency.
The only thing that really differs in the sensations it is the cross that is a little higher it gives a floating sensation. We can love or not that difference is a feeling of history I do not think we played less well because of that but I personally do not see it as a positive.

Conclusion: If you do not want to ruin you and have new equipment and which gives the correct feeling and requiring no adapter you can choose this model.

PS: the internal design differs fundamentally from the role model so in case you want to easily tweak an original controller with this one, I think it is limited and broken jaws.
