No... don't go for a super (think it's the only happs one) that can convert between 4way and 8way. They kinda suck and you can get the functionality out of mame with the setup of up notleft notright, left notup notdown...
Go with either a true 4 way or the oscar plates.
I'm happy with my wico leaf 4way that I got for 10 bucks. But finding them are harder and harder.
but with the optional plates from oscar, the plates are really cool. 4way plate, QBert plate, 2way plates without changing the amount of space!
I'm actually considering adding a super (for round corner games like timepilor) and the plates at some point.
