Interesting responses on the Spanish Eyes, never played this machine,but had read negative & positive opinions,having the bumper down the bottom end of the PF,my impression it was a ball drainer.When I had the oportunity to purchase my Jumping Jack I was a little weary of having bumpers down that end of the machine,so I relyed on the IPDB rating (8.6) - Dont regret it at all,with rebuilt bumpers, very fast machine and quite enjoyable to play.
How much does everyone else rely on the IPDB rating if they are about to purchase a certain machine and have not had a chance to play that machine or cant remember how it played 40+ years ago?
