> Is it the wiimote accessory connector like the pro controller?
And the Nunchuk, yes. For wireless, 8bitdo make a device to use the common Bluetooth controllers like the dualshocks.
Are you talking about this?
If so, is this about the right price and should i look out for bad clones?
Please avoid posting Amazon Super links as you have, they should be trimmed down as follows:

or even further

Oh, and if you pick up one of these you can use a PS3/PS4 controller or a Wii controller with your classic if you want. Or, if you want to keep with the retro theme you can get these controllers too:
This one. And here's one of 8bitdo's retro receivers. They work the same in Bluetooth adapter mode, by the way. But since I'm not seeing a Switch Pro Controller mapping in the Xinput section of the manual, I guess it doesn't work as of now.
If you get one of these you can use them together. :D
