I bought an unfinished Wall cabinet from ebay seller The Gameroom Cabinet.

I must say it is very nice and high quality. Every surface was sanded and ready to paint. All mounting holes are countersunk. The ball return on the inside is pitched so they always come out. The biggest trick is trying to only get "some" balls and not all the balls!

I took it a step further and used a thin sheet of foam from my local craft store and lined the ball return. I also added a volume modification as you can see on the side of the cabinet.

I don't think I would buy another Pachinko without this cabinet I like it so much!
