Not too many 4 spinner games, and the ones there are are usually cocktail: warlords, destruction derby, hot rod, & sprint 4 (and sprint 8 had

OTTOMH. And not much space to put them in working range and not too close to the joysticks (so you don't hit the sticks while using the wheels).
I prefer multiple or modular CPs, though. (I'm planning (still) a three 360 wheel CP to go with my other CPs, 5 ATM.)
OTOH, if you can find the space for three, and like offroad, super sprint, the above games, and can place the spinners so you could play tron and other joy+spinner games (that you like to play), I'd say go for it.
