Since the official adapter isn't available is there a recommended one?
Need to grab that and a GC adapter too.
Speaking of which, do we know if the controllers are going to be limited at all? I'm pretty well covered on GC controllers at the moment, but if these are only going to be available for a year or so and then discontinued I might grab some just to stock up. Kind of wonder about that, since these probably won't be supported for much (if anything) outside of Smash, and outside of a relatively small but hardcore fanbase there probably isn't going to be a lot of interest in them so I kind of doubt Nintendo is going to make them super widely available for a long period of time.
I went with this one:

The reviews were pretty much all positive. There's a slightly bigger one by the same company that also is pretty much all positive reviews too.
