i think it looks great. that color is awesome, and the coin door looks nice...i plan to add one to mine if i ever find a good deal on one.
as for the position of players 3 and 4, they appear to be in very similar position to mine, and i can say they are quite comfortable to use. when playing 4 player TMNT, i prefer Donatello which is player 3, so i frequently use those controls, the angle looks rough, but i is quite comfortable. you also have to remember that you will be about 3 feet from the screen, so it isn't like you are right beside it. you stand with your body at about a 45 degree angle to the screen, your arms sit both at very comfortable angles, just at player 3, your joystick hand is a few inches farther away from your body than your button hand, and the opposite for player 4. I have had quite a few 3 and 4 player game sessions and never once had anyone complain about it.
