This thing is a real mess. It needs a lot and I mean a lot of work. I have contemplated letting it go but this is a real challenge and I will learn a lot from this machine. I was never a huge Defender fan so if I can get it up and running I will probably sell it off to a Defender arcade newbie. It only costs me $150 so if I sell it I will sell it cheap. This is not a business for me. I do it because I love the games.
