I just repaired a Farfalla, and 2 weeks ago - a Devil Rider's (which will be for sale soon). These are really cool games to play and are reliable. I love working on them. If you ever need help, contact David at ;

He is incredibly helpful. Nice game - these are really fun games to play when setup right.

Thanks for the link Nino  I've seen his site before (years ago) and had forgotten about it.
I've sent him an email
