The only good SNES controller for sale these days is the 8bitdo ones. They feel pretty close to the original. If you have or are able to get SNES Classic controllers, you can get a raphnet adapter. Those seem to be identical to the original. I'm a new controller person too. I had watches on SFC controllers for years and would pick them up any time I found a new one for $30ish. If you're patient, that's not a bad option.
