I'm tempted by getting an Arcade 1up but afraid I'll never use it, even if I mod it (I have like 5 devices I've bought for modding purposes and never gotten around to it).
I'm not even sure $199 is a good price for the Simpsons cab considering it only has 2 games. You're really mainly paying for 4 player capability. They're probably gone from my store by now anyway, I went Tuesday and I think they only had 1 left, down from a pallet of like 6. If I do get one, it'll either be a Pac-Man or MK2 legacy edition (if they still have any).
