logitech rumble pad can be had for the pc ... in wireless and wired versions
it's almost exactly like a ps2 controller . I use the cordless version on my mac and play my nes, snes, etc games with it .
the only thing i don't like is for sega emulation, i have to use the shoulder pads (annoying) since there is no 6 [face] button controllers in wireless for pc
but i've manage to use the logitech rumblepad for n64 emulation, the controls take a bit of getting used to in different layout, but you can make it work
use left stick for movement and d-pad for movement
use the right stick for camera (c1, c2, c3, c4)
works out well
