Nothing feels authentic except the real deal. The original stick has very short handle, a rubber centering grommet and leaf switches. You're just not going to approximate that with a centering spring and clicky microswitches.
But if finding and refurbishing an original is out, then you can go with the Reunion- it'll have the short handle. I think the Sanwa can be had with a fairly short handle as well. Or you could go for a 4-way Wico and get the grommet and leafswitches covered, but the handle will be much taller and the throw longer.
I'd probably get the Reunion, it'll play fine and nobody but a hardcore joystick geek will notice or care about the clicky switches, plus it's got a textured red ball that looks closer to the original than the other sticks would.
