Actually, my favorite game of all time is Demolition Derby. I own a dedicated upright, but would really like to find a 4 player cocktail version. Unfortunately, they are nearly impossible to find. For my next project I am planning on making a recreation of the Demolition Derby Cocktail, so that will have 4 (!) 360 wheels and pedals, which should be great for these games.
So yeah, I agree that the spinner deal is not as good, but it's going to have to do for now to tide me over. Plus, with this machine, my Demolition Derby, and potentially a cocktail, that will be all I can fit in my house. Oh, I also have a Firepower pin. See, I'm running out of space!
Anyway, yeah, the spinners might be overkill, but I think it'll be worth the $$$. I have been picking up gas pedals on Ebay, so I will probably end up putting three of them on the Cab.
There was a working offroad at the last auction I was at that went for $100. I probably should have bought it, but I just don't have the room for it. It was worth $100 just for parts.
