I guess that if it was a deserted Island, there would be no power for the pinball, so it has to look good.. So I'll go with Paragon...
It there was power :o I'd still go for Paragon, as I never get tired of it. I love "in line" targets and the spinner shot is just magic when timed right. It is also the best looking pinball. This machine ticks all the boxes for me.. It would be the last pin to go..
